Research Projects

Currently, our research group is involve in three areas of low temperature physics:-

 

● Critical Casimir Forces

In electromagnetism, the Casimir force is due to the confinement of zero-point electromagnetic fluctuations between two conducting plates a finite distance apart. In a completely analogous way, the confinement of critical fluctuation in an adsorbed film leads a thickness dependence correction to the free energy of the film and, therefore a critical Casimir force between the interfaces of the film.

● Supersolid

Torsional oscillator measurements of Eunseong Kim in 2004 found evidence of superflow on solid helium confined in porous Vycor glass with pore diameter of 7 nm, in porous gold with pores of 490 nm and also in bulk solid helium. Very recently Tony Clark and Xi Lin also found evidence of superflow in solid molecular hydrogen. The work in this project aims at elucidating the fascinating properties of this new stare of matter.

● Superconductivity in reduced dimensions

When the diameter of a superconducting wire is smaller than the phase coherence length, its behavior is expected to deviate from that of bulk and crosses over towards that expected of a one-dimensional system. This project aims to elucidate the properties of quasi-one-dimensional superconducting nanowires by studying their electrical transport and thermodynamic properties.  (more… )
