Abstract

The inclusion of strong electronic correlations into a theoretical description of solids is a notoriously hard problem. This review describes various recent schemes to improve on dynamical mean field theory, which includes only local correlations, by systematically incorporating nonlocal correlations as well, and discusses applications to standard models of strongly correlated electrons.
