    • Thermodynamic properties of an integrabel quantum spin ladder with boundary impurities 

      Batchelor, Murray T.; Guan, Xi-Wen; Foerster, Angela; Tonel, Arlei Prestes; Zhou, Huan-Qiang (2003) [Journal article]
      An integrable quantum spin ladder based on the SU(4) symmetry algebra with boundary defects is studied in the framework of boundary integrability. Five nontrivial solutions of the reflection equations lead to different ...
