Detailed measurements of inelastic scattering in Anderson localization

Abstract

Considerable progress has been made in the experimental observation of Anderson localization and quantum eigenstate coherence for electrons in disordered solids. The coherence effects deduced from conductivity measurements require some corrections for inelastic scattering, and often the necessary information is imprecisely known. In this letter we report detailed observations of inelastic effects in an acoustic localization experiment where parameters may be precisely controlled and measured; some phase correlation effects are evident.
