The Vortex State in a Strongly Coupled Dilute Atomic Fermionic Superfluid

Abstract

We show that in a dilute Fermionic superfluid, when the Fermions interact with an infinite scattering length, a vortex state is characterized by a strong density depletion along the vortex core. This feature can make a direct visualization of vortices in Fermionic superfluids possible.
