SOME ASPECTS OF ELECTRON CORRELATION, MAGNETISM, AND LOCALIZATION IN SPATIALLY DISORDERED-SYSTEMS

Abstract:

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 describe the properties of the system in the local moment domains in particular, and their evolution with number density and both structural and electronic parameters of relevance. A probabilisticall...
