    • A supersymmetric U/sub q/[osp(2|2)]-extended Hubbard model with boundary fields 

      Guan, Xi-Wen; Foerster, Angela; Grimm, Uwe; Römer, Rudolf A.; Schreiber, Michael (2001) [Artigo de periódico]
      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 ...
