Proposal requesting support for the

2011 Soft Condensed Matter Physics Gordon-Kenan Research Seminar Soft Matter Far From Equilibrium

For the first time this year, the Soft Condensed Matter Physics Gordon Research Conference (GRC) will be preceded by a Gordon-Kenan Research Seminar (GKRS). The GKRS is a unique forum for graduate students, post-docs, and other scientists with comparable levels of experience and education to present and exchange new data and cutting edge ideas. The GKRS Chair, Alexandra Zidovska, is currently a postdoctoral researcher at Harvard University. The Associate Chair, Aparna Baskaran, has just started this year on a tenure-track faculty position at Brandeis University. This proposal requests I2CAM funding to support the participation of young scientists in the GKRS. This two-day event will run August 13-14, 2011, at Colby-Sawyer College, New London, New Hampshire, to be followed by the Conference on August 14-19 at the same location. The theme of both events is Soft Matter Far From Equilibrium. The systematic study of materials far from equilibrium is rapidly emerging as one of the new frontiers in condensed matter physics. The field of soft condensed matter physics plays a particularly prominent and exciting role in this regard because it investigates a wide range of phenomena, processes and materials for which far-from-equilibrium conditions are a key ingredient. This includes phenomena such as turbulence or fracture, processes like rapid quenching during advanced manufacturing, and whole classes of materials, such as granular matter, that exist inherently far from thermal equilibrium. The complexity of these phenomena and systems presents scientific challenges but also opportunities for new levels of control over materials behavior. For completeness we include below the program of the GRC. The GKRS will start on the day before the GRC and will provide graduate students and postdoctoral fellows in the soft condensed matter physics community with an ideal networking environment, facilitating peer-to-peer scientific discussions in an informal setting. Professional networking at an early career stage is essential, in particular, for an emerging new generation of young scientists working at the interface of physics, biology and materials science. The GKRS will foster scientific exchanges among the younger members of these often separated communities and contribute to develop an early sense of unity. In addition, having gotten to know each other and some of the senior speakers in the informal setting of GKRS, students and postdocs will be more likely to actively participate in the main conference activities, engaging in discussions and setting up contacts and collaborations beneficial for their further professional development. In addition to scientific exchanges and presentations, an important highlight of the GKRS will be a discussion panel focusing on career advancement and transitions such as from graduate school to postdoctoral position and further to junior faculty. The non-intimidating peer-based setting will encourage an exchange of experiences and knowledge in a friendly and open atmosphere and will serve as a great preparation of the participants for the GRC following the GKRS.

Two of the scientific session planned for the GKRS will have a keynote speaker. Erich Sackmann (TU Munich) and Timothy J. Mitchinson (Harvard) have been invited to deliver these lectures. The Mentorship Component will consist of a panel of scientists at various career stages who will discuss career advancement and transitions, providing young investigators with valuable career advice. The panel members are Erich Sackmann (TU Munich), Timothy J. Mitchinson (Harvard), and Cristina Marchetti (Syracuse) on the topic of How to successfully navigate through career transitions. We expect at least 50 GKRS participants. The 2009 Soft Condensed Matter GRC attracted many excellent students and postdocs (about 70 out of a total of 125 partcipants) who took a very active part in the conference. These junior participants expressed strong interest in attending a GKRS in conjunction with the 2011 GRC.

1 Workshop Narrative

The functioning of all cells in biological organisms is based on the complex interaction of many molecular species:proteins, DNA and mRNA molecules, hormones, etc. Vast developments in molecular biology have characterizedmany of the biochemical pathways, but we do not currently understand how they come together to form emergentproperties we observe as the output states of biochemical networks in cells. On one hand we must understand themany body nature of the interactions between the cellular components. On the other hand we are faced with anadditional difficulty, stemming from the nonequilibrium nature of chemical reactions. As a diverse group of youngscientists from different backgrounds, we are organizing a workshop to discuss the role of intrinsic stochasticity inmany-body biochemical networks.

Cells in biological organisms are subject to vast amounts of random variation, which can cause isogenic cells torespond differently, despite identical environmental conditions. Recent experimental techniques make it possible tomeasure this variation in gene expression, protein abundance, and cellular behavior. Combined with computationalmodeling, these techniques enable us to uncover the causes and effects of stochastic cellular dynamics. Dependingon cellular function, biochemical processes may act to minimize stochastic variations or exploit them to the cellsadvantage; in both cases, cellular processes have evolved to be remarkably robust to both intrinsic and extrinsicnoise. By exploring this robustness in naturally occurring biological systems, we hope not only to improve ourunderstanding of cellular biology, but also to formulate the design principles necessary to build similarly robustbiochemical circuits and nanoscale devices.

This workshop will unite a broad array of young, international researchers who work on different aspects ofthe problem of understanding the role of stochasticity in biochemical systems. Experts in developing mathematicalmethods to describe cellular behavior, experimentally analyzing biochemical processes, performing advanced compu-tations of stochastic behavior, and designing novel biological devices will work together to share the latest results inthis exciting area of research and define new research directions for future study.

1.1 Multidisciplinary Investigation

In this workshop, we will bring together several experts from different aspects of this exciting research topic. First,we will hear from experimental molecular biologists, who are continually developing and perfecting new quantitativetechniques to observe single cell and single molecule dynamics. Tools such as flow cytometry and fluorescenceactivated cell sorting (FACS) enable researchers to measure the protein levels for millions of individual living cellsin the time span of a single minutethus conducting millions of simultaneous experiments. Time-lapse fluorescencemicroscopy and microfluidics have made it possible for researchers to measure, track and manipulate the behavior ofsingle cells in carefully controlled micro-environments. Fluorescence in situ hybridization (FISH) techniques enableresearchers to explore the spatial distributions of specific, individual RNA molecules within a cell.

Next, the theorists and mathematicians among us will present new quantitative methods to analyze and explainthe vast amounts of statistical data gathered from such experiments. It is known that stochasticity in cells is caused inpart by intrinsic noise - the variability caused by the statistical dynamics of a chemical reaction with a small numberof reactants - and in part by extrinsic noise - the variability caused by random fluctuations in a cells environment.The participants in this workshop have already developed many methods to understand and differentiate betweenthese types of noise in experimental data. In addition, as experimental techniques such as FISH provide more andmore information on the spatial dynamics of intracellular processes, it becomes more useful to extend these techniquesto spatially heterogenous reaction dynamics.

Finally, these theorists and experimentalists can integrate their various analyses to understand how, why andwhen different cellular mechanisms transmit noise in different ways, i.e. some suppress it while others amplify orexploit it. For example, control theory can help us understand feedback and feedforward regulatory motifs in cellulararchitectures, while an information theoretic perspective can help us to understand how cells in a developing multi-cellular organism can determine their exact spatial location. These analyses suggest new methods and appropriatemodels for mathematically demonstrating how certain motifs are useful for dealing with noise and uncertainty. Suchanalyses are then directly applicable to the work of more applied researchers, who can use these theories to betterconstructing synthetic biological circuits and devices at the nanoscale level, including biomolecular motors and DNAmolecular machines.

Together, the participants of this workshop form an intellectually diverse group of researchers united by theirinterest in the subject of stochasticity in biochemical reaction networks and complex biological matter; they representthe fields of biology, biophysics, engineering, chemistry, mathematics, and computer science. Each has contributedto the field of biochemical networks in either the theoretical or experimental sphere and many have contributed inboth areas.

Despite the great progress made until now in understanding the role of noise in biological regulatory networks,further insight into the functioning of living cells in the presence of physical constraints imposed on them by themolecular nature of their components, can only be made through interdisciplinary collaboration. Only by simultane-ously developing mathematical tools that are appropriately suited for increasingly quantitative experiments, as wellas testing predictions in synthetical molecular architectures and comparing their behavior with regulatory circuitrythat exists in naturally evolved organisms, can we attempt to understand how stochastic molecular interactions resultin predictably functioning cells. The goal of this workshop is to facilitate the interaction of specialists from differentfields, who typically would not meet at more traditional conferences.

1.2 Open and Emerging Questions

Recent advances in experimental molecular biology have revolutionized the way people conduct biological research.Techniques such as flow cytometry, fluorescence activated cell sorting, time-lapse fluorescence microscopy, and mi-crofluidics have made it possible for researchers to measure and manipulate the behavior of single cells and evensingle molecules within them. These experiments have shown that cellular dynamics are intrinsically noisy and thatindividual cells may both regulate and exploit this noise. To further understand the mechanisms of organism devel-opment, evolution, cancer, disease and drug efficacy, we must improve our understanding of the effects of noise on thecorresponding biochemical reaction processes. Such explanations require the close integration of new mathematicalmodels, techniques and theories with these emerging experimental techniques. An improved understanding of thesesystems will help explain newly observed phenomena and may suggest methods by which new behaviors can beengineered.

The main goal of the workshop is to suggest new research directions and new synergies between researchers incomplementary fields within the main field of systems biology. To this end, the workshop will be organized arounda sequence of questions that begins and ends with experimental evidence:

What new experiments are possible and what can they tell us? In the last few years, many of ourparticipants have devised new experimental techniques to measure intracellular dynamics. Even at their infancy,the tools presented at BIRS (September, 2009) have already improved our understanding of intrinsic andextrinsic noise biochemical reaction networks. The particular experimentalists at this workshop will be chosennot only for their excellent laboratory skills but also for their abilities speak the languages of mathematics,computation and control. Their insight into the experimental possibilities (and limitations) is the startingpoint of the workshop.

What are the available computational tools? How good do they need to be? What new mathe-matical approaches may be developed to meet these requirements? The addition of stochasticity togene regulatory network models severely complicates numerical analyses. Several of the workshop participantshave pioneered new techniques for the analysis, reduction, and solution of stochastic processes in the contextof gene regulatory networks and many are extending these results to treat spatially heterogeneous systems. A

2

particular emphasis will be placed upon developing coarse-grained computational analyses in order to tailorbiochemical models to the strengths and limitations of emerging experimental techniques.

How does noise affect cellular mechanisms? How do cellular mechanisms affect noise? Thesignaling network in the cell is vast and only approximately known. Many of our participants have developednew ways to examine control, stability, robustness, adaptability, computation and information transfer underthis highly uncertain setting. In this workshop, the participants will apply these tools to begin answering thequestions of why and when stochasticity is important and what nature can do to exploit and/or diminish theseeffects.

What sorts of synthetic biochemical processes can be designed and constructed? As our compu-tational and theoretical understanding of cell regulation improves, we can obtain more detailed quantitativecharacterizations of biochemical building blocks. Many of our workshop participants in synthetic biology maythen use these design principles to build new organic constructs to perform specific biological and micro-mechanical tasks.

What new experiments should we do? Measurements at the single cell level are difficult, expensive andsometimes even disappointingly uninformative. One of the main objects of this workshop is to suggest newapproaches and collaborations to integrate stochastic modeling and experimental studies. The combination oftheoretical and applied approaches represented in this workshop makes this a particularly exciting question.

2 Workshop Organization

Although other meetings have explored stochasticity in biochemical reaction networks, the proposed workshop willbe unlike any other in the field. The key ingredients that set this workshop apart are (i) a multi-disciplinary andinternational organizing committee and participant list, (ii) an emphasis on young researchers and new ideas ratherthan tenured professors and established techniques, (iii) a flexible schedule with ample discussion time, (iv) a specificfocus on the integration of experimental and theoretical/computational investigations, and (v) integrated live web-casting and teleconferencing for remote participation. Even though we adopt our title and location from two previousWorkshops on Stochasticity in Biochemical Reaction Networks, these ingredients represent a significant shift in focusand organization. The original workshop was organized and attended almost exclusively by researchers connected tothe control engineering community in the USA, whereas this workshop will bring together a multi-disciplinary groupof international researchersincluding not only control engineers, but also physicists, chemists, mathematicians andbiologists (including new organizers). Whereas the original workshops considered mostly theoretical and computa-tional studies of small network circuitries, this workshop will emphasize the systematic integration of computational,theoretical and experimental techniques to investigate the interactions of cellular components at myriad length andtime scales. Moreover, the five-day length of the proposed workshop will allow much more time for discussion andcollaboration than the breakneck pace of the previous two-day workshops. Finally, unlike previous workshops on thistopic, portions of this meeting will incorporate state-of-the-art streaming video and teleconferencing technology tobroadcast live over the Internet, and allow remote participation.

As discussed above, one of the main goals of this workshop is encourage collaboration between researchers fromdiverse fields, who often might not be aware of each others research. The following items will help us to achieve thisgoal.

Diverse organizing committee - The organizers backgrounds are in four different communities: mechanicalengineering (Munsky), computer science (Lampoudi), electrical engineering (Thorsley), and physics (Walczak).One of the key strengths of this workshop, is that we each know and interact with otherwise unconnected groupsof people, who are nonetheless interested in the same questions regarding biochemical stochasticity. The listof invited attendees, who have expressed interest in coming, reflects our ability to bring together differentcommunities.

Emphasis on young researchers We consciously made an effort to invite mainly younger scientists; eitheryoung faculty members, or post-doctoral researchers. Experience in previous workshops has shown us thatsuch a demographic of people just starting their independent research groups, makes it much easier discuss newideas and foster new cross-disciplinary collaborations. We have observed that young, enthusiastic researchersare more prone to engage in lively discussion and they tend to be more flexible with regard to considering newideas. Most importantly, young researchers have a strong professional motivation to create new collaborationsthey can help our workshop, and our workshop can help their careers.

Flexible schedule and emphasis on discussion time The main goal of our workshop is to encouragelong discussions between the participants and foster the exchange of ideas and collaborations. We envision a

3

leisurely schedule with morning talks, flexible afternoon discussions, an hour of pre-dinner lectures, a groupdinner, and an evening with wine and beer in the common room. We will also encourage the speakers to preparetalks that will stimulate discussions, not just show their latest findings. The five day, flexible schedule of theworkshop will allow us to make last minute changes to the program, if needed, to allow for more discussion.

Diverse participant list The workshop participants include representatives of diverse fields: chemists,engineers, control theorists, molecular biologists, physicists, mathematicians and computer scientists. Theseresearchers are also representing a diverse set of locations including US (19), Canada (4), Europe (12) and SouthAmerica (1). Most of the participants are young: 14 are pre-tenure faculty members; 7 will have just startedtheir faculty positions this year; and 6 are currently post-doctoral researchers. At present, we are expecting6 women to attend the workshop: four invited attendees and two organizers, all of them junior faculty (5) orpost-docs (1). This is a high ratio for research disciplines which include such male dominated fields as physics,computer science, engineering and theoretical chemistry.

Because of the unusually young demographic of our workshop, travel aid is particularly important for thisworkshops success. We are requesting financial assistance specifically to help our junior participants whohave limited grants and start-ups funds with which to attend workshops. Our aim is to bring together aninternational group of junior researchers from diverse fields and we are aware that for some people the travelcosts of traveling to Banff are prohibitively expensive.

Ideal venue The Banff International Research Station center is ideally suited for this workshop. Our partic-ipants will have 24-hour access to many common areas with whiteboards and projectors, open wireless access,state-of-the-art webcasting and teleconferencing technology, online library resources and journal access, on-siteaccommodations each computer terminals, and a self-contained campus with excellent dining and recreationfacilities.

Outreach The workshop will take place in the mountain resort town of Banff in Canada. We do notplan on any specific outreach activities during the duration of the workshop. However, seeing that manyattendees are young faculty often involved in formulating the curricula of modern interdisciplinary coursesat their home institutions, we will stimulate informal (and formal on demand) discussions about teaching ofquantified approaches to biochemical networks. For this reason, we will strongly encourage participants to sharetheir presentations, data and computational algorithms for subsequent use in classroom settings. Participantswill be encouraged to publish these pedagogical materials to the workshop website.

Webcasting Due to the high amount of interest in our workshop and the topic of stochastic biochemistry,we plan to add a strong Internet component to this meeting. We will establish a website to help participantscommunicate before and after the workshop and on which we will post speaker abstracts and links to par-ticipant websites. In order to allow for remote participation, we will utilize the Banff International ResearchStations state-of-the-art automated equipment for continuous lecture recording, broadcasting, and integratedteleconferencing.

These Internet technologies will be used to record and broadcast all of the formal lectures and discussions ofrecently published results. However, we plan for the workshop to be flexible to the needs of our participants.Much of the workshop will involve informal discussion of unpublished ideasto increase ease of exchange ofideas and creativity, we will not record these exchanges.

3 Summary

We are organizing a workshop that aims to bring together researchers studying different perspectives on the emergentbehavior of cellular networks. Despite extreme progress over the last decade our understanding of how many cellularcomponents, which interact in an intrinsically stochastic manner, come together and result in reliable outcomes of cellis still in its infancy. The organization of our workshop allows for free discussion between scientists who have beenstudying similar problems with very different tools. Although the large scale goal of understanding the complexity ofcells (the space of possible output states, their relation to biological phenotypes and genotypes, the stability of thesestates, and their connectivity) is clear, the intermediate problems the community needs to solve are not obvious.At this stage of the development of the field it is essential to bring together diverse young scientist to attempt topropose novel approaches to these problems. Our goal is to provide such a venue, introduce scientists from differentfields to each other and encourage informal discussions and strong, long-lasting collaborations.

Event descriptionSoon after the discovery of quantum mechanics, it became evident that the fundamental obstacle to explaining emergent phenomena in solids from first principles is the description of electronic many-body effects.

An important step forward was density-functional theory (DFT) and its local-density approximation (LDA). The success of DFT in explaining the physical and chemical properties of solids is so remarkable, that DFT is considered the standard model of solid-state physics. Nevertheless, LDA and its generalization fail completely for system in which electrons loose their individuality and whose low-energy properties are dominated by electron-electron correlations: Mott insulating transition-metal oxides,

Kondo and heavy-fermion materials, organic crystals, and many others. The realistic description of such strongly-correlated systems remains, to date, one of the grand-challenges of condensed-matter physics.

During the last years, a major breakthrough came with the development of the LDA+DMFT method. In this approach, conventional ab-initio schemes are combined with a modern many-body approach, the dynamical mean-field theory (DMFT).

The aim of the present school is to introduce advanced graduate students and up to this state-of-the-art approach.

The lectures will cover

Overview and Introduction Electron correlations and DMFT Model Hamiltonians Density-functional theory and basis functions Experimental challenges

The LDA+DMFT approach Wannier functions and hopping integrals The screened U: cLDA and cRPA Dynamical Mean-Field Theory LDA+DMFT

DMFT Quantum Impurity Solvers Hirsch-Fye Quantum Monte Carlo Continuous-time QMC Exact diagonalization and Lanczos

Beyond DMFT cluster DMFT and dual Fermions GW+DMFT

The hands-on sessions will include

Wannier functions and model Hamiltonians Dynamical mean-field Theory Hirsch-Fye and continuous-time Quantum Monte Carlo Screened Coulomb Parameters

Exploratory and Novel Aspects: The school should prepare the next generation of students for pushing calculations of strongly correlated materials towards predictive power, thus taking the crucial step needed for rational materials design, realizing novel

functionalities based on emergent phenomena in electronic and energy materials. For this, students need a broad background ranging from ab-initio DFT to many-body theory and quantum Monte Carlo. This background goes across different established and well separated areas of condensed-matter research. It is therefore very difficult to build in regular curricula. To further advance the field, the next generation of students needs to work at the interface of all these research areas and must be able to judge works in all areas involved. The present school aims at advancing the students to the frontiers of research, through a set of comprehensive and pedagogical lectures which cover the essential aspects. The school offers the unique chance of discussing open problems from many perspectives, ranging from experiments to chemistry to ab-initio approaches and many-body physics.

Interdisciplinary Aspects: The school will bring together scientists interested in strongly correlated systems but with a wide variety of expertise: experimental methods, ab-initio DFT-based approaches, many-body techniques, interfacing DFT and many-body methods, quantum chemistry, and massively parallel simulations.

Emerging Questions and Unsolved Problems: At the heart of the school are the experimental and theoretical challenges, which will be presented already on the first day. The discussion of these open and emerging questions will be continued in the course of the school; open problems will be addressed in several of the more advanced lectures, as well as during discussion time. The school will prepare the students to identify the unsolved problems in the field of strong-correlated matter and will work as a catalyzer for new ideas and novel research directions.

Frauenfelder rules: Each 50 minutes lecture is followed by long breaks for discussion and open questions (about 25 minutes). The hands-on sessions offer ample time for gaining working knowledge, asking questions, and clarifications of theoretical aspects.

Plans for integrating young scientists: Several lecturers are young researchers (from the experienced postdoc to the junior professor level). The school is targeted at the next generation of scientists and gives students ample opportunities for interacting with experts; it is the natural springboard to the integration in the scientific community. Students can present posters on their activity.

Reasons to apply for ICAM support: This school is supported by DFG through the German Research Unit FOR1346, Dynamical Mean-Field Approach with Predictive Power for Strongly Correlated Material, and from the Forschungszentrum Jlich. With the funds available we will cover the local and travel expenses of all lecturers, plus local expenses for maximally 30 students, as well as the production of a book of comprehensive lecture notes, that will be distributed to the students at the beginning of the school. Since we cannot cover the travel expenses of students, our funding scheme obviously favors the participation of students from Europe. This is not optimal, because many excellent students which are now approaching the field of strong correlations work outside Europe, and in particular in U.S. universities/laboratories. We ask ICAM

for 5 Junior Travel Awards to support the participation of excellent graduate students/PhD students/early postdocs from U.S. universities/laboratories.

Plans for outreach activities: We will collect lecture notes, which will be published as a book that will be distributed to the students at the beginning of the school (and will also be freely available in electronic format). We expect this book to become an important collection of comprehensive notes on LDA+DMFT for real materials, which will be of wide use in training future students entering the field. The school web-page is http://www2.fz-juelich.de/iff/correl11. Talks, tutorials, and associated material (lectures, lecture notes, examples, test codes, and additional material) will be available on the web through this webpage.

New frontiers in physics of two dimensional electron systems. The physics of two-dimensional electron gases (2DEG) remains at the center stage of modern condensed matter physics. In the late 90's the unexpected observation of a metal-insulator transition in silicon MOSFETs and GaAs hetero-structures brought into question some of the accepted pillars of our understanding of transport in 2D systems. It posed fundamental questions on the role of electron correlations and disorder, which remain widely open and debated. In the 00's we witnessed another unexpected discovery: the realization of a 2D crystal lattice, only 1 atomic layer thick. Graphene research has erupted in condensed matter physics, providing not only fascinating tabletop realization of Dirac fermions in a 2DEG, but also an ideal substrate for novel electronic applications. The dust of these discoveries had not even settled, when Harold Hwang discovered yet another startling class of 2DEG systems in 2004, that again shook the foundations of our understanding. He joined two wide gap band-insulators, SrTiO3 and LaAlO3, and a high mobility 2DEG emerged at the interface. The advances of thin film fabrication techniques with atomically flat surfaces are allowing for a novel 'alchemy' of artificial layered materials, with emergent behavior at the interfaces. The origin of the metallic state of the 2DEG discovered by Hwang remains hotly debated and is surely to be the first surprise of many more coming, as experimentalist begin to fabricate novel oxides heterostructures, including strongly correlated systems. How many physical properties between these different but equally fascinating 2D systems are shared, and what is specific to a given material? What is the role of strong electronic correlations and disorder? Can novel forms of superconductivity be engineered by tweaking these systems? Are fundamentally new theoretical ideas necessary to understand their properties, or old concepts suffice? These basic questions cannot be answered without a gaining a broader perspective on all these systems. The goal of this workshop is to bring together researchers from these three exciting areas, to present the most recent groundbreaking advances, and to promote a fruitful exchange of ideas and experience. We propose to hold this meeting in Buenos Aires, to fulfill the important goal of introducing to the international scientific community this new and remote new node of I2CAM. The proposed dates are 11/24 to 11/26, at the end of the austral spring, with very pleasant weather. Importantly, this workshop will create synergy with the already scheduled International Conference on Recent Progress in Many Body Theories (RPMBT16) to be held in Bariloche (Patagonia) from the 11/28/2011 to 12/02/2011. Due to the convenient time of the academic year and the shared interests between the proposed workshop and the RPMBT, we anticipate a large attendance of about 100 international participants plus 100 locals including 50 students and junior researchers. Note that the enrollment in the Physics program at just at the University of Buenos Aires is about 100 students per year.

Requested funding We request $30K to support registration fees and partial support for travel expenses, in particular for graduate students and young researchers. Air tickets to Argentina, at that time of the year, should be about $1200, from both US and Europe. Local expenses are about half of those in US and Europe, for comparable quality. Plans for integrating young scientists into workshop Scientific events in Argentina, usually enjoy of a large and curious young scientist attendance. This has been the case for the Winter Schools of Physics at the Physics Department of University of Buenos Aires, which have been held yearly since 1998, with more than 50 students attending and coming from all over Latin America. As one of the organizers of the present workshop, has been also been responsible for the organization of several of those Winter Schools (the last one was dedicated to Condensed Matter Physics), we plan to use that previous experience to assure a large attendance of young researchers. In addition, a poster session will allow for young researchers to expose their work and take advantage of interactions with distinguished international visitors. Also building from past successful experiences, we plan to waive the registration fee for young researchers from Latin American countries and dedicate a significant amount of funds to offer support for their travel expenses to Buenos Aires and to Bariloche (by bus is quite inexpensive), so to take advantage of the synergy created by the two scientific events, the I2CAM Worshop and the RPMBT16, mentioned above.

Plans for outreach activities We shall introduce to the general Physics and Biology community of students of University of Buenos Aires, the web-based interactive museum The Emergent Universe. In addition to the promotion of this novel initiative of ICAM, we shall also propose students to engage in the project of translating the contents of the museum and implement a Spanish language version. This will make the museum available to a new audience through out the Latin American region and Spain, and also to the large Spanish speaking community in the US. Plans for webcasting We plan to videotape the seminars and make them available through the web.

2 Workshop narrative

During the past decade there has been enormous interest in the nonequilibrium properties

of many-body systems due to the convergence of a variety of technological and theoretical

advances. On the experimental side, the maturation of the field of cooling and trapping of

atomic/molecular gases has made it possible to access properties of the system at spatial

and temporal scales which would have been inconceivable in solid-state condensed matter

systems. At the same time, it has made it possible to design systems with interesting

properties and to simulate non-trivial model Hamiltonians capturing strong correlations

and disorder. There have also been many other experimental advances in fabrication and

measurement techniques that have made it possible to probe non-equibrium and dynamical

properties of a range of low-dimensional and mesoscopic/nanoscale systems consisting of

quantum dots, carbon nanotubes, graphene, Josephson junctions, one-dimensional quantum

wires, quantum Hall edges, superconducting nanowires/films etc. in the presence of applied

bias voltages, fields, microwaves etc. These experimental advances promise a revolution in

both the quality and quantity of information about nonequilibrium processes in the near

future.

On the theoretical side there have been corresponding advances as well. The study of

noise correlations in transport has been advanced by the notion of Full Counting Statistics,

which produces the generating function of all noise correlators. Powerful methods of Con-

formal Field Theory and Bethe ansatz have been used to predict the generic behavior of

zero- or one-dimensional systems where a parameter (such as the coupling constant or the

temperature) is quenched (changed abruptly) or the system is driven out-of-equilibrium by a

large bias/field etc. This is complemented by generalizations of renormalization group, scal-

ing and flow equation ideas as well as various computational methods and Greens function

1

methods to study these problems. For higher-dimensional systems, large-scale computation

has been used to investigate the approach to thermal equilibrium from initial conditions far

from equilibrium. Last but not least, gauge/gravity dualities originally developed in the

context of String Theory have found application in describing strongly coupled condensed

matter systems, both in equilibrium and nonequilibrium.

Advances on the experimental and theoretical front have generated a lot of excitement

and interest in questions of non-equilibrium in diverse communities studying a variety of

systems and techniques and have helped underline and formulate important problems ahead

of us. It has become clear that in spite of the advances, even the conceptual understanding of

non-equilibrium systems has many challenges, even more so for strongly correlated systems.

In terms of theoretical techniques, generalizations of various methods has been sought but

is far from complete. It is the right time to have critical discussions about the validity

of various generalizations and comparisons between various techniques. In addition, the

refinement of experimental techniques to access interesting regimes, the extraction of relevant

non-equilibrium properties and the conceptual and theoretical interpretation of experimental

measurements, all present additional challenges.

Besides being of fundamental interest in condensed matter, nonequilibrium phenomena

are also of interest to the Quantum Computing community for two generic reasons: Firstly,

noise and decoherence are ubiquitous in any substrate, and a better understanding of these

phenomena could be a step towards mitigating its consequences. Secondly, any operation to

be performed necessarily happens in a finite time, and is a nonequilibrium process. General

questions about nonequilibrium are also relevant for other branches of physics as well as

to other disciplines such as biology and chemistry and some of the topics and challenges

discussed in the workshop are expected to have broad implications.

The time seems ripe for a workshop/school on nonequilibrium phenomena. The orga-

nizers, some of whom have already contributed to the growing literature on nonequilibrium,

and others who aspire to enter this exciting field, wanted to provide a forum where graduate

students, postdocs, and faculty who want to learn more about this field can do so from

the ground up, with minimal assumptions about prior knowledge. We also did not want

to perpetuate the somewhat artificial classical/quantum divide, and have chosen to include

both with a view to presenting the overlaps and differences and to generate an interchange of

ideas between the two communities. The choice of lecture series outlined in the next section

accentuates this viewpoint and illustrates the interdisciplinary nature and implications of

the proposed workshop.

The proposed workshop is expected to have lots of time for questions and open discussions

not only after and in between talks but also by having a pedagogical setting as well as by

having a presence of many young researchers. In addition, having the lodging and boarding

facility for all participants at the same location (i.e. within the IISER campus) will greatly

facilitate informal discussions during and after meals and allow for dynamic scheduling of

discussion sessions on questions of interest as the workshop evolves.

3 Plans for integrating young scientists into workshop

The format of the school is designed with the goal of educating graduate students/postdocs

in mind. We expect a total participation of about 60-100 people, with at least half being

students, and at least a quarter being postdocs. The bulk of the time will be spent on

Lecture Courses by prominent researchers in the field. Each lecture will last for 1.5 hours,

with different topics (to be described soon) taking up 3 to 5 lectures. These lecture courses

will be interspersed by 1.5 hour talks by leading theorists and experimentalists to give a

picture of our current understanding of nonequilibrium, and also by short talks (half an

hour) by postdocs and faculty on recent results.

The sequence of lecture topics is designed to take a smart student who has finished

coursework on statistical mechanics and solid state physics all the way to being capable of

conducting research. The rough ordering and length is as follows, with details of the contents

of each course and the scheduling to be described in the following sections:

Nonequilibrium Bosonization (Igor Gornyi, 3 lectures, References[46, 47, 48, 49, 50,51, 52, 53, 54, 55, 56, 57]).

Fluctuation Theorems (Alex Altland, 3 lectures, References[58, 59, 60, 61, 62, 63, 64]) Glassy Systems (Letitia Cugliandolo, 3 lectures, References[65, 66, 67, 68, 69, 70, 71]) AdS/CMT (Sumit Das, 3 lectures, References[72, 73, 74, 75, 76, 77]) Active Systems (Sriram Ramaswamy, 3 lectures, References[78, 79, 80, 81])All the lecturers named above (some of whom are also organizers) have already been

contacted and expressed their willingness to attend the school.

We now turn to a brief description of the contents of each set of lectures. Note that there

is some overlap between different sets of lectures. This is intentional; we want the students

to see the same method from different points of view, and to see them applied to different

problems.

4 Plans for outreach activities

We plan to have an open evening in an easily accessible venue in Kolkata in which the

public can interact with the workshop organizers and interested participants. They could ask

questions related to the topic of the workshop and beyond and about doing physics (PhD in

6

physics, job opportunities, working as a scientist, scientific process etc.). Kids and students

of different age groups, parents, teachers, science enthusiasts, and other varied cross-section

of society can get an opportunity to interact with an international group of scientists and

vice-versa and have a lot of time to chat and have informal discussions. Given that there

is only a limited time for a public event during the course of a workshop, this event will

put more emphasis on open, informal and dynamic discussion between public and a whole

community of scientists in keeping with the spirit and theme of the workshop.

5 Plans for Webcasting

We plan to make all the lecture courses available online for the benefit of the participants

as well as the wider community interested in the topic.

6 Budget Justification

Since IISER Kolkata will be covering boarding and lodging for all the participants, the

budget consists mainly of travel costs and incidental expenses (such as transportation from

Kolkata to the IISER campus).

We have requested funding for full reimbursement of all the school lecturers (8 out of 10

are affiliated to ICAM branches) to the International Center for Theoretical Sciences (ICTS).

We have also requested from ICTS full reimbursement for all students/postdocs traveling

within India to the winter school, the expected number being around 80. In addition we

have requested partial support for invited speakers.

The block travel awards amount of $65,000 requested from ICAM is estimated as fol-

lows: (i) Travel reimbursement for students and postdocs travelling from abroad including

travel from emerging nations (estimated cost $40,000) (ii) Travel reimbursement for invited

speakers (including a good number of young faculty) travelling from abroad (estimated cost

$20,000) (iii) Travel reimbursement for some faculty/scientists travelling from emerging na-

tions (estimated cost $5,000).

In addition we are requesting a general workshop support amount of $2000 specifically

towards funding the outreach event discussed above.
