Mean field phase diagrams of imbalanced Fermi gases near a Feshbach resonance

Abstract

We propose phase diagrams for an imbalanced (unequal number of atoms or Fermi surface in two pairing hyperfine states) gas of atomic fermions near a broad Feshbach resonance using mean field theory. Particularly, in the plane of interaction and polarization we determine the region for a phase separation phase composed of normal and superfluid components. We compare our prediction of phase boundaries with the recent measurment, and find a good qualitative agreement.
