Classification of integrable clusters of classical Heisenberg spins
Marco Ameduri, Bogomil Gerganov, Richard A. Klemm
In this letter we present a general classification of integrable models of identical classical spins coupled via the isotropic Heisenberg Hamiltonian. Our constructive proof of int…
On the Beta Function for Anisotropic Current Interactions in 2D
B. Gerganov, A. LeClair, M. Moriconi
By making use of current-algebra Ward identities we study renormalization of general anisotropic current-current interactions in 2D. We obtain a set of algebraic conditions that en…
Integrable Marginal Points in the N-Cosine Model
Bogomil Gerganov
The integrability of the N-cosine model, a N-field generalization of the sine-Gordon model, is investigated. We establish to first order in conformal perturbation theory that, for…
On the Integrability of the Bukhvostov-Lipatov Model
Marco Ameduri, Costas J. Efthimiou, Bogomil Gerganov
The integrability of the Bukhvostov-Lipatov four-fermion model is investigated. It is shown that the classical model possesses a current of Lorentz spin 3, conserved both in the bu…
