Many-particle quantum walks in disordered media — •Felix R. Anger1,2, Sibylle Braungardt2, and Andreas Buchleitner2 — 1Fakultät für Physik, Ludwig-Maximilians-Universität München — 2Physikalisches Institut, Albert-Ludwigs-Universität Freiburg
The problem of many-particle transport through disordered media lies at the heart of a multitude of physical processes. We study quantum walks on a biased beam splitter array as a simple model for the time evolution of many-particle states in a disordered potential. Using a general expression for the particle number correlation functions, we characterize the transport properties of such systems by investigating the dependence of localization phenomena on the number of injected particles as well as on their entanglement.
