Influence of Coulomb disorder on the phase diagram of the Anderson-Hubbard model

Institute of Physics

We study the half-filled Hubbard model with Anderson and Coulomb disorder by mean of dynamical mean field theory using the geometrically averaged local density of states. The paramagnetic phase diagram of the model at zero temperature as a function of the Coulomb interaction and Anderson disorder strength is obtained. The influence of Coulomb disorder on the correlated metal, Mott and Anderson insulator phases is considered and discussed.
