Mott--Hubbard transition vs. Anderson localization of correlated, disordered electrons

Strongly Correlated Electrons 2009-11-10 v1 Disordered Systems and Neural Networks

Abstract

The phase diagram of correlated, disordered electrons is calculated within dynamical mean--field theory using the geometrically averaged (''typical'') local density of states. Correlated metal, Mott insulator and Anderson insulator phases, as well as coexistence and crossover regimes are identified. The Mott and Anderson insulators are found to be continuously connected.
