The Hubbard model is the simplest model of interacting fermions on a lattice and is of similar
importance to correlated electron physics as the Ising model is to statistical mechanics or the …

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

A review of the basic ideas and techniques of the spectral density-functional theory is
presented. This method is currently used for electronic structure calculations of strongly …

In the early 1970s, Wilson developed the concept of a fully nonperturbative renormalization
group transformation. When applied to the Kondo problem, this numerical renormalization …

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 …

Materials with correlated electrons exhibit some of the most intriguing phenomena in
condensed matter physics. A new theoretical framework is now allowing theorists to …

Inelastic light scattering is an intensively used tool in the study of electronic properties of
solids. Triggered by the discovery of high-temperature superconductivity in the cuprates and …

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 …

We introduce an extension of the dynamical mean-field approximation (DMFA) that retains
the causal properties and generality of the DMFA, but allows for systematic inclusion of …

We present release 1.3 of the ALPS (Algorithms and Libraries for Physics Simulations)
project, an international open-source software project to develop libraries and application …
