Minimal Unitary Models and The Closed SU(2)-q Invariant Spin Chain

Abstract

We consider the Hamiltonian of the closed $SU(2{)}_q$ invariant chain. We project a particular class of statistical models belonging to the unitary minimal series. A particular model corresponds to a particular value of the coupling constant. The operator content is derived. This class of models has charge-dependent boundary conditions. In simple cases (Ising, 3-state Potts) corresponding Hamiltonians are constructed. These are non-local as the original spin chain.
