Mott--Hubbard and Anderson Transitions in Dynamical Mean--Field Theory
arXiv:cond-mat/0502257 · doi:10.1016/j.physb.2005.01.177
Abstract
The Anderson--Hubbard Hamiltonian at half--filling is investigated within dynamical mean--field theory at zero temperature. The local density of states is calculated by taking the geometric and arithmetic mean, respectively. The non--magnetic ground state phase diagrams obtained within the different averaging schemes are compared.
