12 Jan 2007 | | Subject: | Superconductivity | | Abstract: | The superfluid properties of a two-state Fermi mixture in an optical lattice are profoundly modified when an imbalance in the population of the two states is present.We present analytical solutions for the free energy, and for the gap and number equations in the saddle-point approximation describing resonant superfluidity in the quasi-two-dimensional gas. Inhomogeneities due to the trapping potentials can be taken into account using the local density approximation. Analyzing the free energy in this approximation, we find that phase separation occurs in the layers. The phase diagram of the superfluid and normal phases is derived and analytical expressions for the phase lines are presented. We complete the investigation by accounting for effects beyond mean-field in the BEC limit where the system is more properly described as a Bose-Fermi mixture of atoms and molecules. | | Source: | arXiv, cond-mat/0701272 | | Services: | Forum | Review | PDF | Favorites | |
