Momentum isotropisation in random potentials
arXiv:1209.1477 · doi:10.1140/epjst/e2013-01756-8
Abstract
When particles are multiply scattered by a random potential, their momentum distribution becomes isotropic on average. We study this quantum dynamics numerically and with a master equation. We show how to measure the elastic scattering time as well as characteristic isotropisation times, which permit to reconstruct the scattering phase function, even in rather strong disorder.
