Mott-Hubbard transition versus Anderson localization in correlated electron systems with disorder.
نویسندگان
چکیده
The phase diagram of correlated, disordered electron systems is calculated within dynamical mean-field theory using the geometrically averaged ("typical") local density of states. Correlated metal, Mott insulator, and Anderson insulator phases, as well as coexistence and crossover regimes, are identified. The Mott and Anderson insulators are found to be continuously connected.

First - and Second Order Phase Transitions in the Holstein - Hubbard Model
– We investigate metal-insulator transitions in the half-filled Holstein-Hubbard model as a function of the on-site electron-electron interaction U and the electron-phonon coupling g. We use several different numerical methods to calculate the phase diagram, the results of which are in excellent agreement. When the electron-electron interaction U is dominant the transition is to a Mott-insulato...
متن کاملFlatband Localization in the Anderson-falicov-kimball Model
Recent studies have shown a new disorder-induced insulator-metal transition (MIT) of one-electron states, called the ”inverse Anderson transition”. The existence of this transition becomes already visible for noninteracting particles when the system has highly degenerated localized states forming a flatband. In a flatband localized states may melt into extended states due to disorder. For weak ...
متن کاملFerromagnetism and Metal–Insulator Transitions in Correlated Electron Systems with Alloy Disorder
Alloy disorder can affect ferromagnetism and metal–insulator transitions of correlated lattice fermion systems in subtle and often unexpected ways. Solving the Hubbard model and the periodic Anderson model within dynamical mean-field theory we show that alloy disorder can increase the Curie temperature of a non-disordered system, and also yields novel Mott or Kondo insulators at fractional elec...
متن کاملRapid Note Mott transition of the f-electron system in the periodic Anderson model with nearest neighbor hybridization
We show analytically that, under certain assumptions, the periodic Anderson model and the Hubbard model become equivalent within the dynamical mean field theory for quasiparticle weight Z → 0. A scaling relation is derived which is validated numerically using the numerical renormalization group at zero temperature and quantum Monte Carlo simulations at finite temperatures. Our results show that...
متن کاملMetal-insulator transitions in the periodic Anderson model.
We solve the periodic Anderson model in the Mott-Hubbard regime, using dynamical mean field theory. Upon electron doping of the Mott insulator, a metal-insulator transition occurs which is qualitatively similar to that of the single band Hubbard model, namely, with a divergent effective mass and a first order character at finite temperatures. Surprisingly, upon hole doping, the metal-insulator ...
