On domain wall boundary conditions for the XXZ spin Hamiltonian
Domenico Orlando, Susanne Reffert, Nicolai Reshetikhin
In this note, we derive the spectrum of the infinite quantum XXZ spin chain with domain wall boundary conditions. The eigenstates are constructed as limits of Bethe states for the finite XXZ spin chain with quantum sl(2) invariant boundary conditions.
