Finite Temperature Phase Diagram of Quasi-Two-Dimensional Imbalanced
Fermi Gases Beyond Mean-Field

M. A. Resende, A. L. Mota, R. L. S. Farias, Heron Caldas
We investigate the superfluid transition temperature of quasi-two-dimensional imbalanced Fermi gases beyond the mean-field approximation, through the second-order (or induced) interaction effects. For a balanced Fermi system the transition temperature is suppressed by a factor $\approx 2.72$. For imbalanced Fermi systems, the polarization and transition temperature of the tricritical point are significantly reduced as the two-body binding energy $|\epsilon_B|$ increases.
