The Anderson-Mott transition
The interacting disordered electron problem is reviewed with emphasis on the quantum phase transitions that occur in a model system and on the field-theoretic methods used to describe them. An elementary discussion of conservation laws and diffusive dynamics is followed by a detai1ed derivation of the extended nonlinear sigma model, which serves as an effective field theory for the problem. A g...

متن کاملDoping-dependent studies of the Anderson-Mott localization in polyaniline at the metal-insulator boundary
Temperature-dependent dc conductivity measurements and infrared reflectivity measurements ~20–9000 cm! were performed on a series of polyaniline samples with two different dopant acids at various doping levels. The typical fingerprints of a disordered metal such as a positive temperature coefficient of resistivity at high temperatures, a very high reflectivity in the far infrared, and a plasma ...
متن کاملDisorder screening near the Mott–Anderson transition
Correlation-driven screening of disorder is studied within the typical-medium dynamical mean-field theory (TMT–DMFT) of the Mott–Anderson transition. In the strongly correlated regime, the site energies eR characterizing the effective disorder potential are strongly renormalized due to the phenomenon of Kondo pinning. This effect produces very strong screening when the interaction U is stronger...
متن کاملMott-Hubbard transition versus Anderson localization in correlated electron systems with disorder.
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.
