The BCS model and the off shell Bethe ansatz for vertex models

Abstract

We study the connection between the BCS pairing model and the inhomogeneous vertex model. The two spectral problems coincide in the quasi–classical limit of the off–shell Bethe Ansatz of the disordered six vertex model. The latter problem is transformed into an auxiliary spectral problem which corresponds to the diagonalization of the integrals of motion of… (More)
