The Vortex State in a Strongly Coupled Dilute Atomic Fermionic Superfluid

TL;DR

This paper demonstrates that in a strongly interacting dilute Fermionic superfluid, vortices exhibit significant density depletion along their cores, enabling potential direct visualization of vortices.

Contribution

It reveals the vortex structure in strongly coupled dilute Fermionic superfluids, highlighting a prominent density depletion that aids visualization.

Findings

Vortices have strong density depletion in the core.

Visualization of vortices becomes feasible.

Vortex characteristics are linked to strong fermion interactions.

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.
