Correlated lattice fermions in high dimensions
1990
Preserved Fulltext
We discuss the properties of correlated lattice fermions in the limit of high dimensions d -» <*>. In this limit theoretical investigations are enormously simplified, while at the same time correlations remain non-trivial. Contact to finite dimensions can be made via systematic 1/d-expansions. We review the state-of-art of this new approach.
