Yz. Zhang et Hq. Zhou, 9 CLASSES OF INTEGRABLE BOUNDARY-CONDITIONS FOR THE 8-STATE SUPERSYMMETRIC FERMION MODEL, Journal of physics. A, mathematical and general, 31(34), 1998, pp. 7051-7059
Nine classes of integrable boundary conditions for the eight-state sup
ersymmetric model of strongly correlated fermions are presented. The b
oundary systems are solved by using the coordinate Bethe ansatz method
and the Bethe ansatz equations for all nine cases are given.
