    • Algebraic properties of an integrable t-J model with impurities 

      Foerster, Angela; Links, Jon; Tonel, Arlei Prestes (1999) [Artigo de periódico]
      We investigate the algebraic structure of a recently proposed integrable t-J model with impurities. Three forms of the Bethe ansatz equations are presented corresponding to the three choices for the grading. We prove that ...

    • Exact solution for the Bariev model with boundary fields 

      Foerster, Angela; Guan, Xi-Wen; Links, Jon; Roditi, Itzhak; Zhou, Huan-Qiang (2001) [Artigo de periódico]
      The Bariev model with open boundary conditions is introduced and analysed in detail in the framework of the Quantum Inverse Scattering Method. Two classes of independent boundary reflecting -matrices leading to four different ...

    • Integrable open boundary conditions for the Bariev model of three coupled XY spin chains 

      Foerster, Angela; Gould, M.D.; Guan, Xi-Wen; Roditi, Itzhak; Zhou, Huan-Qiang (2001) [Artigo de periódico]
      The integrable open-boundary conditions for the Bariev model of three coupled one-dimensional XY spin chains are studied in the framework of the boundary quantum inverse scattering method. Three kinds of diagonal boundary ...
