Journal ArticleDOI
Dynamical mean-field theory of strongly correlated fermion systems and the limit of infinite dimensions
TL;DR: The dynamical mean field theory of strongly correlated electron systems is based on a mapping of lattice models onto quantum impurity models subject to a self-consistency condition.
Journal ArticleDOI
Anomalous diffusion in disordered media: Statistical mechanisms, models and physical applications
TL;DR: In this article, the authors consider the specific effects of a bias on anomalous diffusion, and discuss the generalizations of Einstein's relation in the presence of disorder, and illustrate the theoretical models by describing many physical situations where anomalous (non-Brownian) diffusion laws have been observed or could be observed.
Journal ArticleDOI
Hubbard model in infinite dimensions
Antoine Georges,Gabriel Kotliar +1 more
TL;DR: This work presents an exact mapping of the Hubbard model in infinite dimensions onto a single-impurity Anderson (or Wolff) model supplemented by a self-consistency condition, which provides a mean-field picture of strongly corrrelated systems, which becomes exact as d\ensuremath{\rightarrow}\ensure math{\infty}.
Journal ArticleDOI
Dynamical singlets and correlation-assisted Peierls transition in VO2
Silke Biermann,Silke Biermann,A. I. Poteryaev,A. I. Poteryaev,Alexander I. Lichtenstein,Antoine Georges,Antoine Georges +6 more
TL;DR: It is found that VO2 is not a conventional Mott insulator, but that the formation of dynamical V-V singlet pairs due to strong Coulomb correlations is necessary to trigger the opening of a Peierls gap.
Journal ArticleDOI
Strong Correlations from Hund’s Coupling
TL;DR: In this article, the authors review the theoretical understanding and physical properties of these Hund's metals, together with the relevance of this concept to transition-metal oxides (TMOs) of the 3D, and especially 4d, series (such as ruthenates), as well as to the iron-based superconductors (iron pnictides and chalcogenides).
