A supersymmetric U/sub q/[osp(2|2)]-extended Hubbard model with boundary fields
(2001) [Journal article]A strongly correlated electron system associated with the quantum superalgebra Uq[osp(2|2)] is studied in the framework of the quantum inverse scattering method. By solving the graded reflection equation, two classes of ...
