New integrable 1D models of superconductivity
Marius de Leeuw, Anton Pribytok, Ana L. Retore +1
In this paper we find new integrable one-dimensional lattice models of electrons. We classify all such nearest-neighbour integrable models with su(2)xsu(2) symmetry following the p…

Towards the solution of an integrable spin chain
Rafael I. Nepomechie, Rodrigo A. Pimenta, Ana L. Retore
Two branches of integrable open quantum-group invariant quantum spin chains are known. For one branch (epsilon=0), a complete Bethe ansatz solution has been propose…
