Bethe Ansatz solution for quantum spin-1 chains with boundary terms

Abstract

The procedure for obtaining integrable open spin chain Hamiltonians via reflection matrices is explicitly carried out for some three-state vertex models. We have considered the 19-vertex models of Zamolodchikov-Fateev and Izergin-Korepin, and the Z2Z_{2}-graded 19-vertex models with sl(21)sl(2|1) and osp(12)osp(1|2) invariances. In each case the eigenspectrum is determined by application of the coordinate Bethe Ansatz.
