Backscattering echo of correlated wave packets [PDF]
Nicolas Cherroret, Dominique DelandeWe present an analytical theory describing a novel phenomenon of enhanced backscattering corresponding to the spatial refocussing of a spread-out correlated wave packet due to a brief interaction with a disordered potential. Our theory is validated by numerical simulations and explains the physics observed in recent experiments on cold atom transport in disorder.View original: http://arxiv.org/abs/1306.6838
