Superfluid properties of a Bose-Einstein condensate in an optical lattice confined in a cavity
arXiv:0708.2196 · doi:10.1016/j.optcom.2008.01.039
Abstract
We study the effect of a one dimensional optical lattice in a cavity field with quantum properties on the superfluid dynamics of a Bose-Einstein condensate(BEC). In the cavity the influence of atomic backaction and the external driving pump become important and strongly modify the optical potential. Due to the strong coupling between the condensate wavefunction and the cavity modes, the cavity light field develops a band structure. This study reveals that the pump and the cavity emerges as a new handle to control the superfluid properties of the BEC.
