Algebraic Bethe Ansatz for the Open XXZ Spin Chain with Non-Diagonal Boundary Terms via 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…
-invariant non-compact boundary conditions for the XXZ spin chain
Dmitry Chernyak, Azat M. Gainutdinov, Hubert Saleur
We introduce new -invariant boundary conditions for the open XXZ spin chain. For generic values of we couple the bulk Hamiltonian to an infinite-dimensional…
Davydov-Yetter cohomology and relative homological algebra
Matthieu Faitg, Azat M. Gainutdinov, Christoph Schweigert
Davydov--Yetter (DY) cohomology classifies infinitesimal deformations of the monoidal structure of tensor functors and tensor categories. In this paper we provide new tools for the…
