"Localization of ultra-cold bosons in a 3D laser speckle disordered potential."

"We have observed 3D localization of ultra-cold atoms of a Bose Einstein Condensate, suspended against gravity, and released in a 3D optical disordered potential with short correlation lengths in all directions. Fluorescence imaging of the expanding cloud yields density profiles composed of a steady localized part and a diffusive part. A phenomenological analysis of the data allows us to determine the localized fraction and the diffusion coefficients of the diffusing part. I will present and discuss these results, in the context of Anderson localization."
