Algebraic Bethe ansatz for open XXX model with triangular boundary matrices
arXiv:1209.4269 · doi:10.1007/s11005-012-0601-6
Abstract
We consider open XXX spins chain with two general boundary matrices submitted to one constraint, which is equivalent to the possibility to put the two matrices in a triangular form. We construct Bethe vectors from a generalized algebraic Bethe ansatz. As usual, the method also provides Bethe equations and transfer matrix eigenvalues.
