Integrable model of interactingXXand Fateev-Zamolodchikov chains
Francisco Castilho Alcaraz, R Z Bariev
We consider the exact solution of a model of correlated particles, which is presented as a system of interacting XX and Fateev-Zamolodchikov chains. This model can also be considered as a generalization of the multiband anisotropic t - J model in the case where we restrict the site occupations to at most two electrons. The exact solution is obtained for the eigenvalues and eigenvectors using the Bethe ansatz method.
