Metal-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 ...
متن کاملLevel curvature and metal-insulator transition in 3d Anderson model
The level curvature in the Anderson model on a cubic lattice is numerically investigated as an indicator of the metallic-insulator transition. It is shown that trie mean curvature obeys a scaling law in the whole range of the disorder parameter. In the metallic regime, the distribution of rescaled curvatures is found to be well described by a formula proposed by Zakrzewski and Delande [1] for r...
متن کاملMetal-insulator transitions in the Falicov-Kimball model with disorder
The ground-state phase diagrams of the Falicov-Kimball model with local disorder are derived within the dynamical mean-field theory and using the geometrically averaged s“typical”d local density of states. Correlated metal, Mott insulator, and Anderson insulator phases are identified. The metal-insulator transitions are found to be continuous. The interaction and disorder compete with each othe...
متن کاملSurface States, Surface Metal-Insulator, and Surface Insulator-Metal Transitions ∗
I present an informal discussion of various cases where two-dimensional surface metal-insulator structural and charge-density-wave instabilities driven by partly filled surface states have been advocated. These include reconstructions of clean semiconductor surfaces and of W(100) and Mo(100), as well as anomalies on the hydrogen-covered surfaces H/W(110) and H/Mo(110), and possibly alkali-cover...
