| Popis: | The Bethe ansatz solutions for an open XXZ spin chain with arbitrary spin with N sites and nondiagonal boundary terms are revisited. The anisotropy parameter, for cases considered here, has values \eta = i \pi r/q, where r and q are positive integers with q restricted to odd integers. Numerical results are presented to support the solutions. Comment: 22 pages; v2: references added; Some comments added; revised version with more sections, numerical results and updated references |
