Cold Atomic Gases in Optical Lattices with Disorder

Abstract

Cold atomic gases placed in optical lattices enable studies of simple con-densed matter theory models with parameters that may be tuned relativelyeasily. When the optical potential is randomized (e.g. using laser speckle tocreate a random intensity distribution) one may be able to observe Andersonlocalization of matter waves for non-interacting bosons, the so-called Boseglass in the presence of interactions, as well as the Fermi glass or quantumspin glass for mixtures of fermions and bosons.PACS numbers: 03.75.Kk, 03.75.Lm, 05.30.Jp, 64.60.Cn
