In the last two decades non-equilibrium spectroscopies have evolved from avant-garde
studies to crucial tools for expanding our understanding of the physics of strongly correlated …

The study of nonequilibrium phenomena in correlated lattice systems has developed into
one of the most active and exciting branches of condensed matter physics. This research …

Metal-insulator transitions are accompanied by huge resistivity changes, even over tens of
orders of magnitude, and are widely observed in condensed-matter systems. This article …

We review the dynamical mean-field theory of strongly correlated electron systems which is
based on a mapping of lattice models onto quantum impurity models subject to a self …

This article reviews quantum cluster theories, a set of approximations for infinite lattice
models which treat correlations within the cluster explicitly, and correlations at longer length …

The ordinary single-channel Kondo model consists of one or more spin-½ local moments
interacting antiferromagnetically with conduction electrons in a metal. This model has …

The calculation of the electronic properties of materials is an important task of solid-state
theory, albeit particularly difficult if electronic correlations are strong, eg, in transition metals …

A systematic study of optical and transport properties of the Hubbard model, based on the
Metzner-Vollhardt dynamical mean-field approximation, is reviewed. This model shows …

Abstract The Falicov-Kimball model was introduced in 1969 as a statistical model for metal-
insulator transitions; it includes itinerant and localized electrons that mutually interact with a …

The zero-temperature transition from a paramagnetic metal to a paramagnetic insulator is
investigated in the dynamical mean field theory for the Hubbard model. The self-energy of …
