EXPERIMENTAL MATERIAL SCIENCE GROUP

Dr. Mahavir Singh

Dr. Nainjeet Singh Negi

Dr. Nagesh Thakur

Dr. Vir Singh Rangra

Experimental group in Physics Department is currently working on various

multifunctional materials such as Nanomaterials, Ferrites, multiferroic, ferroelectric,

chalcogenide glasses and shock wave induced synthesis of newer materials.

Ferrites, multiferroic, ferroelectrics, nanostructural materials and

chalcogenide glasses

Complex perovskite oxides exhibit a rich spectrum of properties including magnetism,

ferroelectricity, multiferroic properties, strong correlated electron behaviour and

magnetoresistance, which have been a great interest of research in recent years

� In nano ferrites, there exist the possibility of enhancement of surface based properties

like magnetic and electrical. We have widely studied Ni-Zn, Mn-Zn and Mg-Mn

ferrites

� Natural multiferroic single phase components are rare and their magnetoelectric

responses are either relatively weak or occurs at temperatures too low for practical

applications. In contrast, multiferroic composites which incorporate ferroelectric and

ferri-/ferromagnetic phases, typically yield giant magnetoelectric coupling response

above room temperature which makes them area of research for technological

applications. We have studied BiFeO3 and Fe doped PbTiO3

� Miniaturization of components is highly required in next generation of these devices.

Therefore deposition of nanostructured ferrolectric thin films is one ways for

miniaturizing components. Very little has been reported so far on development of

nanostructural ferroelectric thin films. Fe doped (Pb, Sr)TiO3 nanostructured thin

films have been studied in detail.

.

Particle Physics Research Group

The group is working in the frontier areas of neutrino physics viz solar neutrinos, double beta

decay processes and nuclear structure calculations for nuclear astrophysics. The group has

produced some excellent research work as evidenced by research publications in reputed

international research journals. In the next five years, the group will be focusing on various

aspects of neutrino physics including solar and atmospheric neutrinos, lepton mass matrices,

neutrino less double beta decay and nuclear structure and transfer reactions for nuclear

astrophysics. The group is engaged in constraining the neutrino and solar astrophysical

parameters in the light of the latest solar neutrino data from SNO, KamLAND, Super

Kamiokande and other solar neutrino experiment like GNO etc. The group is eagerly awaiting

the data from the forthcoming Borexino experiment, which is expected to start taking data very

soon. The group has embarked upon an ambitious programme to work on the refinement of the

Large Mixing Angle Solution( LMA) and investigate the scope of other subdominant transitions in

the resolution of the solar neutrino problem subject of a worldwide experimental and theoretical

effort. The group is initiating a major programme to constrain the lepton mass matrices from the

solar and atmospheric neutrino data and constrain the multiplicity of unified models beyond the

Standard Model. It is expected that some of the models can be ruled out on the basis of neutrino

phenomenology combined with other particle data.

Nuclear Physics and Astrophysics

The main research interests are focused on the strongly interacting finite and infinite nuclear matter

within the framework of Effective Field Theory (EFT) and Exact Renormalization Group (RG), and EFT

and Density Function (DFT) of Mean filed theory. We are also interested to understand the

stable/unstable color superconducting phases of quark matter in the interior of compact stars. The results

of nuclear models in conjunction with General Relativity can employed to study the Rapid rotation of

compact stars, Cooling of compact stars, Stellar pulsation, Mass accrection onto compact stars, and

Gravity-wave instability in rotating compact stars. This is relevant to experiments that are planned at

nuclear physics facilities and, astrophysically, to the structure of compact stars

OBJECTIVES:

1. Carry out frontline research in the thrust areas at the forefront of scientific activities in

theoretical Nuclear Physics and Astrophysics

2. Develop theoretical and phenomenological expertise and specific tools to analyse and

explain data of ongoing future national and international experimental facilities in nuclear

physics and compact stars.

3. Contribute to the human resource development in theoretical nuclear physics through

training of person in advanced basic science research.

Condensed Matter Research Group

Condensed matter physics group is working in classical fluids, quantum fluids and soft condensed

matter. In classical liquids, we have studied the dynamic and transport properties of LJ fluids, liquid

metals and expanded liquid metals.

Presently, the major work we are carrying out to study the mass dependence of mutual diffusion

in Lennard- Jones fluids by MD simulation and to study the transport properties of LJ fluids in the

presence of wave vector q. In the former case there is no experimental data is available for the mass

dependence of Mutual diffusion. Here we will study the self as well as mutual diffusion by the mean

square displacement method and by integrating the time correlation function relevant to the diffusion

coefficient . The self- diffusion coefficient of respective particle will be calculated from the mean square

displacement of the particle 1 and 2. For this we need the position particles at various times which we

can have from the trajectories of the particle. On the other hand we can also calculate the self diffusion

coefficient of particles 1 and 2 from the velocity auto correlation function ( VACF) using Green Kubo

formula. But for the Mutual diffusion we have to calculate the relative velocity correction function. For

this we need the velocities of two particles at different times. For position and velocities of the

particles. During simulation the temperature of the system will be kept constant and the system will be

left for equilibrated for 20,000 time steps.

The time correlation function has provided a powerful tool for the theoretical prediction of

transport properties. In this approach the transport properties are related to the time integrals of the time

correlation function of appropriate fluxes. The time correlation function may be obtained using Mori

Zwanzig formalism or one may also assume a phenomenological form for the correlation function,

which is then imposed to yield the exact short time expansion, of the function. The Mori- Zwanzig

formalism provides the continued fraction representation for the time correlation function in terms of

memory function. Memory function can be obtained using either a microscopic approach or some

phenomenological arguments. The success of this approach depends on the exact knowledge of the first

frequency sum rules, i.e. moments of the short time expansion of the correlation function.

Expression for the first few non- vanishing moments relevant to the calculation of the diffusion

coefficient, viscosity and thermal conductivity are available in literature. Here, we are interested in

deriving the first few non- vanishing moments of the heat flux correlation function by including the

enthalpy fluctuations in the presence of wave vector q. Expressions obtained so far will be further used

to calculate the thermal conductivity of Lennard Jones fluids.

It will be a first step to study the effect of wave vector on the behaviour of time correlation

function and hence to the thermal conductivity. The same procedure will be used to study the other

properties like viscosity and self diffusion later on.

The third problem is to study the dynamic excitation in electron fluid by using Mori’s memory

function formulism. Here the dynamic density and spin density response function will be expressed in

terms of their corresponding static susceptibilities and memory kernels. An exact microscopic

calculation of the memory kernel is not feasible and we will in the mode coupling approximation. The

formulism will provides us a set of coupled equations to be solved self consistently for the dynamic

excitation spectrum of the electron fluid. This approach will be further extended to the coupled layer

systems.

Particle Physics Research Group

First Year Plan:

It is proposed to subject the Large mixing Angle Solution to deeper scrutiny and Constrain the

neutrino and solar astrophysical parameters in the light of the latest solar neutrino data.

Second Year Plan:

It is proposed to examine the scope for other subdominant transitions, which can coexist with the

dominant LMA transitions in the light of the solar neutrino data . The role of other subdominant

transitions driven by the possible neutrino magnetic moment and the transitions into sterile

neutrinos in the solution of the solar neutrino problem will be examined in detail.

Third Year Plan:

The role of weakly mixed sterile neutrinos in the resolution of the remaining neutrino anomalies

viz. the lack of spectral upturn at low energies and the low Argon production rate in Home stake

contrary to the LMA expectations will be examined.

Fourth Year Plan:

The evidence for time modulations of the solar neutrino flux with the rotation period of the Sun

reported by the Stanford group is expected to crystallize by his time especially because of the

availability of data from the forthcoming solar neutrino experiments especially Borexino. It is

proposed to examine this evidence carefully and construct models to explain these time variations

if found real.

Fifth Year Plan

It is proposed to constrain the neutrino mass matrices in particular and the lepton mass matrices in

general in the light of the vast amount of solar, atmospheric and terrestrial neutrino data. An

unified picture of quark and lepton mixing matrices will be sought which will be used to examine

the phenomenological viability of different classes of Grand Unified models. It is expected that the

study will rule out many of the GUT models found in the literature.

CONDENSED MATTER (THEORY)

In the first year we will derive the expression for the frequency sum rules of heat flux correlation

function and at the same time the MD simulation for the mass dependence will be in progress.

In the second year we will do some analytical calculations for thermal conductivity in the

memory function approach. The numerical calculations will also be done in the same year. MD

simulation will remain in progress side by side. In the third year, we will write the manuscript and send it

for publication.

In the fourth year, we will derive expression for the frequency sum rules of the transverse stress

correlation function. We will derive expression for zeroth, second and fourth sum rules of the transverse

stress auto correlation function. At the same time Mori’s memory function formulism and mode coupling

approximation will be standard for the dynamic excitations in electron fluid.

In the fifth year, we will carry out the analytical calculations for the coefficient of shear

viscosity. The numerical calculations will also be done in the same year. The problem of electron fluid

will remain in progress aside by side.

In the next year we will write the manuscript and send it for publication
