Absence of diffusion in wave dynamics

Abstract

We present a first-principles study of wave dynamics in random slabs by solving the Bethe-Salpeter equation including weak localization. The pulse evolution in space and time shows anomalous nondiffusive behavior. This is in agreement with microwave studies of nonexponential decay of pulsed transmission and explains recent optical pulsed measurements.
