摘要: We give a precise definition for excitations consisting of droplet size n in the XXZ chain with various choices boundary conditions, including kink conditions and prove that, each n, energies converge to condition independent value thermodynamic limit. rigorously compute an explicit formula this limiting using Bethe ansatz.
