Phase diagram of the rotating two-component Fermi gas including vortices

TL;DR

This paper maps the phase diagram of a rotating two-component Fermi gas, identifying conditions for superfluidity with and without vortices based on various physical parameters.

Contribution

It provides a comprehensive phase diagram for a rotating two-component Fermi gas, including vortex and non-vortex superfluid phases, considering multiple physical parameters.

Findings

Superfluidity occurs under specific rotation frequencies and interaction strengths.

Vortex formation depends on rotation speed and population imbalance.

The phase diagram delineates regions of superfluid and normal phases.

Abstract

We determine the conditions under which superfluidity with and without quantized vortices appears in a weakly interacting two-component atomic Fermi gas that is trapped in a rotating cylindrical symmetric harmonic potential. We compute the phase diagram as a function of rotation frequency, scattering length, temperature, total number of trapped atoms, and population imbalance.
