Abstract
The ground state phase diagram of the extended Hubbard model for arbitrary electron density is investigated with the broken-symmetry Hartree approximation. It is found that for two-sublattice orderings, only the charge-order and the antiferromagnetism exist without the mixed phase.
Das Phasendiagramm des Grundzustands des ausgedehnten Hubbardmodells fur beliebige Elektronendichte wird mit der Hartree-Naherung gebrochener Symmetrie untersucht. Es wird gefunden, das fur Zwci-Untergitter-Ordnungszustande nur die Ladungs-Ordnung und der Antiferromagnetismus ohne Mischphase existieren.
