I think it is fairto invite at this Festa chearful guest:the Cooper pair

They wear a crown:spin up or spin down

They stay togetheronly in cold weather

and can even shield

a magnetic field

The Coopers dream

to master the stream

to surf-ride and flee

from the Fermi sea.

but can anyone save

them from a d-wave?

The Coopers hate

the polaron state.

There’s much more fun

in a bipolaron!

Fermions want their shares

within boson pairs

The game gets quite funny

(reminds Don Giovanni),

but yields something novel:

a Boson-Fermion model.

localized bi-polarons and delocalized fermions (Annette Bußmann-Holder & Roman Micnas)

In such furious dance

no one knows at once

who’s single out of three:

it’s supersymmetry!

Who’s the good man

causing such nesting?

Some are suggesting

the apex-oxygen

Heinz Bilz proposed

that such ability

comes from nonlinear

polarizability.

“Do ruthenates

have triplet pairs?”

Georg meditates

with a cup of Marsala.

This is the worst

of all nightmares,

a real kabbàla!”

The Coopers need

increase their speed.

That’s why they like

to ride a good bike

Karl-Alex, the master,

wants them even faster;

but, rather than striving

in an awful rodeo,

he wants them to drive

an Alfa Romeo!

they like a large Alfa!

FIAT

ALFA Montreal 4.9

Should we believe

in this awful threat?

Science confirms:

it’s a real effect!

“Superconductors

-Paul is informing –

-will solve the problem

of global warming”

and thank you very much Annette, Hugo and Davor!

Happy birthday, Alex and Georg!

Great science keeps you twenteenager
