Radial quadrupole and scissors modes in trapped Fermi gases across the BCS phase transition
Michael Urban
The excitation spectra of the radial quadrupole and scissors modes of ultracold Fermi gases in elongated traps are studied across the BCS superfluid-normal phase transition in the…
Pair-Breaking in Rotating Fermi Gases
Michael Urban, Peter Schuck
We study the pair-breaking effect of rotation on a cold Fermi gas in the BCS-BEC crossover region. In the framework of BCS theory, which is supposed to be qualitatively correct at…
Coupling of hydrodynamics and quasiparticle motion in collective modes of superfluid trapped Fermi gases
M. Urban
At finite temperature, the hydrodynamic collective modes of superfluid trapped Fermi gases are coupled to the motion of the normal component, which in the BCS limit behaves like a…
Temperature and finite-size effects in collective modes of superfluid Fermi gases
M. Grasso, E. Khan, M. Urban
We study the effects of superfluidity on the monopole and quadrupole collective excitations of a dilute ultra-cold Fermi gas with an attractive interatomic interaction. The system…
Non-standard pairing in asymmetric trapped Fermi gases
Paolo Castorina, Marcella Grasso, Micaela Oertel +2
We study an ultracold trapped Fermi gas of atoms in two hyperfine states with unequal populations. In this situation the usual BCS pairing is suppressed and non-standard pairing me…
Two-fluid model for a rotating trapped Fermi gas in the BCS phase
Michael Urban
We investigate the dynamical properties of a superfluid gas of trapped fermionic atoms in the BCS phase. As a simple example we consider the reaction of the gas to a slow rotation…
