The Mott Transition and F Electron Physics
The Mott transition, namely the metal–insulator transition (MIT) driven by electron–electron interactions, is a fascinating phenomenon realized experimentally in many compounds such as V2O3 and Ni(Se,S)2. It was suggested many years ago by Johansson that the Mott transition concept is also relevant to elements in the lanthanide and actinide series. The development of dynamical mean–field method...
متن کاملElectronic Liquid Crystal Phases in Hole Doped Mott Insulators
Theoretical, numerical, and experimental studies have suggested the existence of ‘striped’ electronic phases in doped antiferromagnets such as the high temperature superconductors. We survey the literature and summarize the results.
متن کاملMott transition and Kondo screening in f-electron metals.
We study how a finite hybridization between a narrow correlated band and a wide conduction band affects the Mott transition. At zero temperature, the hybridization is found to be a relevant perturbation, so that the Mott transition is suppressed by Kondo screening. In contrast, a first-order transition remains at finite temperature, separating a local-moment phase and a Kondo-screened phase. Th...
متن کاملMott transition from a diluted exciton gas to a dense electron-hole plasma in a single V-shaped quantum wire
We report on the study of many-body interactions in a single high-quality V-shaped quantum wire by means of continuous and time-resolved microphotoluminescence. The transition from a weakly interacting exciton gas when the carrier density n is less than 10 cm ~i.e., naX,0.1, with aX the exciton Bohr radius! to a dense electron-hole plasma (n.10 cm, i.e., naX.1) is systematically followed in the...
متن کاملThe 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...
