Stationary Vortices and Pair Currents in a Trapped Fermion Superfluid

We examine the effects of stationary vortices in superfluid 6Li atoms at zero temperature in the frame of the recently developed fluiddynamical scheme, that includes the pair density and its associated pair current and pair kinetic energy in addition to the fields appearing in the hydrodynamical des...
