The operator content of the exactly integrable SU(N) magnets
Francisco Castilho Alcaraz, Marcio Jose Martins
The operator content of the exactly integrable models associated with the SU(N) Lie algebras, with periodic boundaries, are studied. The authors' results were obtained from a numerical and analytical analysis of the associated Bethe-ansatz equations. The resulting spectra indicate that the ferromagnetic and antiferromagnetic models have different operator content for N>2, being realizations of distinct modular invariant solutions.
