Strong Anderson localization in cold atom quantum quenches
arXiv:1311.2268 · doi:10.1103/PhysRevLett.112.110602
Abstract
Signatures of strong Anderson localization in the momentum distribution of a cold atom cloud after a quantum quench are studied. We consider a quasi one-dimensional cloud initially prepared in a well defined momentum state, and expanding for some time in a disorder speckle potential. Anderson localization leads to a formation of a coherence peak in the \emph{forward} scattering direction (as opposed to the common weak localization backscattering peak). We present a microscopic, and fully time resolved description of the phenomenon, covering the entire diffusion--to--localization crossover. Our results should be observable by present day technology.
