  • Abstract: General mathematical theorem tell us that all states in 1D random potentials are exponentially localized. Recent experiments with Bose-Einstein condensates in optical speckle potentials, however, appear to show mobility edges that are due to potential correlations.
    In this talk, I will show that there is no contradiction between theorems and experiment. Our calculations beyond lowest order perturbation theory clearly highlight the interesting role of potential correlations in the multiple scattering by impurities which eventually lead to Anderson localized states.
