The Open XXZ Model with Lattice Supersymmetry (Mathematical Physics seminar)
Robert Weston will review some of the background of models with lattice SUSY and highlight the need for a more systematic understanding of how the SUSY fits into our otherwise thorough description of these models within the QISM picture. As a first step to developing such an understanding, he will explain a theorem that gives the commutation relations of the SUSY operators with the generators of the reflection algebra. The action of the SUSY operators on Bethe states follows simply from this theorem, and the results provide a different and hopefully useful characterisation of the ground state.
