Effects of polarization, rotation and tunneling in the unitary Fermi gas

This event is part of the Condensed Matter Theory Seminar Series.

I will present recent theoretical predictions concerning the role of interactions in the unitary regime of a trapped Fermi gas. These include the effect of polarization and the consequences on the density profiles, the behavior of the spin excitation in the normal phase, the effect of an adiabatic rotation which causes, in the absence of vortices, phase separation between a superfluid and a normal rotating component, and finally the tunneling properties of the gas in the presence of a 1D optical lattice.
