New Integrable Generalization of the One-Dimensional t-J Model

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/151836A new generalization of the t-J model with a nearest-neigbour hopping is formulated and solved exactly by the Bethe-ansatz method in the thermodymanic limit. The model describes the dymanics of fermions with different spins and with isotropic and anisotropic interactions.12 pages, latexStatistical MechanicsNew Integrable Generalization of the One-Dimensional t-J Modeltext
