Location of the vortex phase in the phase diagram of a rotating two-component Fermi gas

摘要

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. Our analysis is based on solving the Bogoliubov-de Gennes equation.
