27 Mar 2015 | | Abstract: | We study multiple period states of a superfluid Fermi gas in an optical
lattice along the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstein condensate
(BEC) crossover. The existence of states whose period is a multiple of the
lattice spacing is a consequence of the non-linear behavior of the gas, which
is due to the presence of the order parameter associated with superfluidity. By
solving Bogoliubov-de Gennes equations we find that, in the BCS side of the
crossover, the multiple period states can be energetically favorable compared
to the normal Bloch states and their survival time against dynamical
instability drastically increases, suggesting that these states can be
accessible in current experiments with ultracold gases. This is in sharp
contrast to the situation in BECs. | | Source: | arXiv, 1503.7976 | | Services: | Forum | Review | PDF | Favorites | |
