Spin Vertex Models and Quantum Algebras

Doron Gepner (Department of Particle Physics and Astrophysics, Weizmann Institute, Rehovot 76100, Israel)

We construct new solvable vertex models based on the spin representation of the Lie algebra Bk. We use these models to study the algebraic structure underlying such vertex theories. We show that all the Bk spin vertex models obey a version of the BMW algebra along with extra relations that are called n–CB (conformal braiding) algebras. These algebras were discussed before for various IRF (interaction round the face) models. Here we establish that the same algebras hold for vertex models.
