Strong electronic correlations pose one of the biggest challenges to solid state theory.
Recently developed methods that address this problem by starting with the local, eminently …

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 …

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 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 …

We study the evolution of a Mott-Hubbard insulator into a correlated metal upon do** in
the two-dimensional Hubbard model using the cellular dynamical mean-field theory. Short …

Using cluster perturbation theory, it is shown that the spectral weight and pseudogap
observed at the Fermi energy in recent angle resolved photoemission spectroscopy of both …

This is a short review of the theoretical work on the two-dimensional Hubbard model
performed in Sherbrooke in the last few years. It is written on the occasion of the twentieth …

We study the Mott transition, antiferromagnetism, and superconductivity in layered organic
conductors using the cellular dynamical mean-field theory for the frustrated Hubbard model …

Proximity to a Mott insulating phase is likely to be an important physical ingredient of a
theory that aims to describe high-temperature superconductivity in the cuprates. Quantum …

Dynamical mean field theory (DMFT), combined with finite-temperature exact
diagonalization, is one of the methods used to describe electronic properties of strongly …
