Collective excitations in a doped antiferromagnet

Abstract

Developpement d'une procedure systematique d'etude d'un antiferromagnetique dope, dans le regime de couplage intermediaire. A partir de la solution Hartree-Fock du modele de Hubbard dans le cas de la bande a moitie pleine, on obtient le spectre d'onde de spin, et on trouve qu'a la limite du couplage fort, le mode d'onde de spin est identique a celui obtenu a partir du modele du spin 1/2 d'Heisenberg correspondant. On evalue de facon autocoherente, la correction a une boucle de l'aimantation du sous reseau due aux excitations d'ondes de spin. Etude de l'evolution de l'aimantation du sous-reseau en fonction de U/t
