Superfluid transition in quasi-two-dimensional Fermi gases
We show that atomic Fermi gases in quasi-two-dimensional (2D) geometries are promising for achieving superfluidity. In the regime of BCS pairing for weak attraction, we calculate the critical temperature T{sub c} and analyze possibilities of increasing the ratio of T{sub c} to the Fermi energy. In t...

| description | We show that atomic Fermi gases in quasi-two-dimensional (2D) geometries are promising for achieving superfluidity. In the regime of BCS pairing for weak attraction, we calculate the critical temperature T{sub c} and analyze possibilities of increasing the ratio of T{sub c} to the Fermi energy. In the opposite limit, where a strong coupling leads to the formation of weakly bound quasi-2D dimers, we find that their Bose-Einstein condensate will be stable on a long time scale. |
