Description
The unitary Fermi gas has emerged as one of the most
fascinating objects of study in the last decade with an wide
impact on various physics sub-fields, from nuclear physics
and astrophysics, AdS/CFT, to condensed matter physics. A
unitary Fermi gas has remarkable properties, among them: the
highest critical temperature known of a superfluid system
(in appropriate units), the highest critical Landau
velocity, a pseudogap phase and a FFLO phase. I will first
describe briefly the nature and main properties of unitary
gas. This will be followed by a description of an extension
of the Density Functional Theory to superfluid systems, both
in its static and time-dependent from, its validation and
verification, and finally a number of simulations of vortex
generation and dynamics in such systems, which reveal some
unexpected features, among them the possibility of superflow
with supercritical Landau velocity.
