Self-consistent study of Anderson localization in the Anderson-Hubbard model in two and three dimensions
Self-consistent study of Anderson localization in the Anderson-Hubbard model in two and three dimensions
We consider the change in electron localization due to the presence of electron-electron repulsion in the Anderson-Hubbard model. Taking into account local Mott-Hubbard physics and static screening of the disorder potential, the system is mapped onto an effective single-particle Anderson model, which is studied within the self-consistent theory of electron …
