Probing ultracold Fermi gases with light-induced gauge potentials
arXiv:1102.1399 · doi:10.1103/PhysRevA.83.053619
Abstract
We theoretically investigate the response of a two component Fermi gas to vector potentials which couple separately to the two spin components. Such vector potentials may be implemented in ultracold atomic gases using optically dressed states. Our study indicates that light-induced gauge potentials may be used to probe the properies of the interacting ultracold Fermi gas, providing. amongst other things, ways to measure the superfluid density and the strength of pairing.
