Ferromagnetism in Correlated Electron Systems: Generalization of Nagaoka's Theorem

Marcus Kollar, Rainer Strack, Dieter~Vollhardt

Nagaoka's theorem on ferromagnetism in the Hubbard model with one electron less than half filling is generalized to the case where all possible nearest-neighbor Coulomb interaction…
