The solution of an open XXZ chain with arbitrary spin revisited
Rajan Murgan, Christopher Silverthorn
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…

Generalized T-Q relations and the open spin-s XXZ chain with nondiagonal boundary terms
Rashad Baiyasi, Rajan Murgan
We consider the open spin-s XXZ quantum spin chain with nondiagonal boundary terms. By exploiting certain functional relations at roots of unity, we derive a generalized form of T-…
