Abstract: | We investigate a mix-dimensional Fermi-Fermi mixtures in which one species is confined in two-dimensional (2D) space while the other is free in three-dimensional space (3D). We determine the superfluid transition temperature T c for the entire BCS-BEC crossover including the important effects of noncondensed pairs. We find that the transition temperature reduces while the imbalance of mass is increased or lattice spacing is reduced. In spin imbalance case, the stability of superfluid is sharply destroyed by increasing the polarization. |
