Interpolation between Hubbard and supersymmetric t-J models. Two-parameter integrable models of correlated electrons

Abstract

Two new one-dimensional fermionic models depending on two independent parameters are formulated and solved exactly by the Bethe-ansatz method. These models connect continuously the integrable Hubbard and supersymmetric t-J models.
