We study the exact solution of a superconducting model of strongly correlated electrons in 1+1 dimensions. We explain the method of solution and explicitly derive the fundamental Bethe equations that determine the physical properties of the model in the thermodynamic limit. We also give explicit expressions for the conserved quantum integrals of motion in the model and prove a lowest weight theorem for the Bethe Ansatz states.

Commuting Transfer Matrices

A new completely integrable model of strongly correlated electrons is proposed which describes two competitive interactions: one is the correlated one-particle hopping, the other is the Hubbard-like interaction. The integrability follows from the fact that the Hamiltonian is derivable from a one-parameter family of commuting transfer matrices. The Bethe ansatz equations are derived by algebraic Bethe ansatz method.
