INTERPLAY BETWEEN DISORDER AND ELECTRON INTERACTIONS - MEAN-FIELD PHASE-DIAGRAM OF AN ANDERSON-HUBBARD MODEL

To obtain a broad understanding of the combined effects of disorder and electron interactions, the phase diagram of a half-filled Gaussian site-disordered Anderson-Hubbard model is assessed numerically on a simple cubic lattice, at the unrestricted Hartree-Fock mean field level. Metallic/insulating...
