SOME ASPECTS OF ELECTRON CORRELATION, MAGNETISM, AND LOCALIZATION IN SPATIALLY DISORDERED-SYSTEMS
We consider a disordered Hubbard model for a system characterized by quenched liquid-like disorder, with correlation treated at the generalized Hartree-Fock level and the possibility of local magnetic moments introduced from the outset. A simple theory based on averaged Green functions is used to de...
