New Integrable Generalization of the One-Dimensional t-J Model
F. C. Alcaraz, R. Z. Bariev
Abstract
A 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.
