A Note on the Symmetry Algebra of An Asymmetric XXZ Quantum Spin Chain
M. A. Rego-Monteiro
We show that an interesting open asymmetric XXZ quantum spin chain with surface fields is invariant under a two-parametric generalization of the slq(2) algebra with deformation parameters being a particular root of unit.

Bethe Ansatz for the Open XXZ Chain from Functional Relations at Roots of Unity
We briefly review Bethe Ansatz solutions of the integrable open spin-1/2 XXZ quantum spin chain derived from functional relations obeyed by the transfer matrix at roots of unity.
