Diffusion of cold atomic gases in the presence of an optical speckle potential
arXiv:0912.1117 · doi:10.1103/PhysRevA.81.033612
Abstract
We consider diffusion of a cold Fermi gas in the presence of a random optical speckle potential. The evolution of the initial atomic cloud in space and time is discussed. Analytical and numerical results are presented in various regimes. Diffusion of a Bose-Einstein condensate is also briefly discussed and similarity with the Fermi gas case is pointed out.
