Integrable Coupling in a Model for Josephson Tunneling Between Non-Identical BCS Systems
Abstract
We extend a recent construction for an integrable model describing Josephson tunneling between identical BCS systems to the case where the BCS systems have different single particle energy levels. The exact solution of this generalized model is obtained through the Bethe ansatz.
