Algebraic Bethe ansatz for 19-vertex models with upper triangular K-matrices
arXiv:1406.5757 · doi:10.1088/1742-5468/2014/11/P11007
Abstract
By means of an algebraic Bethe ansatz approach we study the Zamolodchikov-Fateev and Izergin-Korepin vertex models with non-diagonal boundaries, characterized by reflection matrices with an upper triangular form. Generalized Bethe vectors are used to diagonalize the associated transfer matrix. The eigenvalues as well as the Bethe equations are presented.
