Equivalent isotropic Osp(2/2) spin chains and its Bethe ansatz analysis
Marcio Jose Martins, P B Ramos
Abstract
In this paper we discuss the equivalence between two integrable and isotropic Osp(2/2) chains via the braid-monoid approach. We use the analytical Bethe ansatz approach in order to solve the spectrum of these systems. The ground state is parametrized by a special structure of the Bethe ansatz roots. Their interpretation in terms of correlated fermionic models is briefly discussed.
