Heisenberg XXX Model with General Boundaries: Eigenvectors from Algebraic Bethe Ansatz
Samuel Belliard, Nicolas Crampé
We propose a generalization of the algebraic Bethe ansatz to obtain the eigenvectors of the Heisenberg spin chain with general boundaries associated to the eigenvalues and the Beth…
Integrable Boundary for Quad-Graph Systems: Three-Dimensional Boundary Consistency
Vincent Caudrelier, Nicolas Crampé, Qi Cheng Zhang
We propose the notion of integrable boundary in the context of discrete integrable systems on quad-graphs. The equation characterizing the boundary must satisfy a compatibility equ…
Coordinate Bethe Ansatz for Spin s XXX Model
Nicolas Crampé, Eric Ragoucy, Ludovic Alonzi
We compute the eigenfunctions and eigenvalues of the periodic integrable spin s XXX model using the coordinate Bethe ansatz. To do so, we compute explicitly the Hamiltonian of the…
Scattering matrix for a general gl(2) spin chain
S. Belliard, N. Crampe, E. Ragoucy
We study the general L_0-regular gl(2) spin chain, i.e. a chain where the sites {i,i+L_0,i+2L_0,...} carry the same arbitrary representation (spin) of gl(2). The basic example of s…
