Algebraic Bethe Ansatz for the Open XXZ Spin Chain with Non-Diagonal Boundary Terms via $U_{\mathfrak{q}}{\mathfrak{sl}}_2$ Symmetry

Dmitry Chernyak, Azat M. Gainutdinov, Jesper Lykke Jacobsen +1

We derive by the traditional algebraic Bethe ansatz method the Bethe equations for the general open XXZ spin chain with non-diagonal boundary terms under the Nepomechie constraint…
