| * ABSTRACT | |||||||
| The dynamical mean-field theory has been successful in describing many important properties of strongly correlated systems. In a standard single-site dynamical mean-field theory where local quantum dynamics is fully included, spatial correlations are treated only within a mean-field approximation. Several generalized versions have been proposed to properly incorporate spatial fluctuations, which become more important in lower dimensions. In this talk I will give a review of one promising generalization, the cellular dynamical mean-field theory, with stress on its derivation, technical details, and some results up to date. | |||||||
