The Bethe Ansatz

Yang permutation i.z.cm.y

This model is the further generalization of the Gaudin-Yang model to an arbitrary permutation group. The solution was provided by C.N. Yang in 1967.Yang.PRL.19. All previously-mentioned models with \(\delta\)-interaction can be viewed as special cases of this more general model.
