Three-band Anderson-Mott-Hubbard model for the metal-insulator transition in cubic disordered tungsten bronzes NaxWO3 and NaxTayW1-gamma O3

Abstract:

A microscopic three-band Anderson-Mott-Hubbard model for cubic disordered tungsten bronzes NaxWO3 and NaxTayW1-yO3 is studied over a range of doping levels x-y at the level of an unrestricted Hartree-Fock approximation in order to understand the effects of disorder and electron interaction on the electronic ground state and their implications for the chemically induced metal-insulator transition observed at least in the latter materials. For sufficiently large U a pseudogap develops at EF in ...
