INTERPLAY BETWEEN DISORDER AND ELECTRON INTERACTIONS IN A D=3 SITE-DISORDERED ANDERSON-HUBBARD MODEL - A NUMERICAL MEAN-FIELD STUDY
We consider a numerical mean-field study, at the unrestricted Hartree-Fock level, of a Gaussian site-disordered Anderson-Hubbard model on a simple cubic lattice. The phase diagram at half filling is obtained, including magnetic and metallic-insulating phases, and all relevant phase boundaries are fo...
