Delocalization by nonlinearity and interactions in systems with disorder — •Dima Shepelyansky — Laboratoire de Physique Theorique, CNRS, Univ. P.Sabatier
Analytical and numerical studies are presented showing that in disordered systems with Anderson localization nonlinearity, or interactions between quantum particles, lead to delocalization of probability in space. Relation of this phenomenon to various experimental situations is briefly discussed.
