Integrable Deformations of the XXZ Spin Chain
Niklas Beisert, Lucas Fievet, Marius de Leeuw +1
We consider integrable deformations of the XXZ spin chain for periodic and open boundary conditions. In particular, we classify all long-range deformations and study their impact o…

Open Perturbatively Long-Range Integrable gl(N) Spin Chains
N. Beisert, F. Loebbert
We construct the most general perturbatively long-range integrable spin chain with spins transforming in the fundamental representation of gl(N) and open boundary conditions. In ad…
