Title: Generalized Gutzwiller method for n{ge}2 correlated bands: First-order metal-insulator transitions

Abstract

We have generalized the Gutzwiller method to the cases of n{ge}2 correlated bands and report studies on a degenerate two-band model with Hund{close_quote}s rule type on-site interactions. At half band filling the metal-insulator transitions are usually of first order. {copyright} {ital 1997} {ital The American Physical Society}
