Contribution

It introduces a comprehensive phase diagram incorporating Mott and Anderson insulators, highlighting their continuous connection within a unified theoretical framework.

Findings

Identified correlated metal, Mott insulator, and Anderson insulator phases.

Mapped coexistence and crossover regimes.

Established the continuous connection between Mott and Anderson insulators.

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.
