Exact diagonalization of the generalized supersymmetric t-J model with boundaries
Abstract
We study the generalized supersymmetric t-J model with boundaries in three different gradings: FFB, BFF and FBF. Starting from the trigonometric R-matrix, and in the framework of the graded quantum inverse scattering method (QISM), we solve the eigenvalue problems for the supersymmetric t-J model. A detailed calculations are presented to obtain the eigenvalues and Bethe ansatz equations of the supersymmetric t-J model with boundaries in three different backgrounds.
