Quantum chains with a Catalan tree pattern of conserved charges: The Δ=−1 XXZ model and the isotropic octonionic chain
A class of quantum chains possessing a family of local conserved charges with a Catalan tree pattern is studied. Recently, we have identified such a structure in the integrable SU(N)-invariant chains. In the present work we find sufficient conditions for the existence of a family of charges with this structure …
