Ansatz de Bethe algébrico com fronteiras triangulares
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, , 26/05/2014)In this work we study vertex models with non-diagonal boundaries, characterized by reection matrices with an upper triangular form. By means of an extension of the algebraic Bethe ansatz, we construct generalized Bethe ...
