The Bethe ansatz approach for factorizable centrally extended S-matrices
M. J. Martins, C. S. Melo
We consider the Bethe ansatz solution of integrable models interacting through factorized -matrices based on the central extention of the symmetry. The respective…
On the solution of a supersymmetric model of correlated electrons
M. J. Martins, P. B. Ramos
We consider the exact solution of a model of correlated electrons based on the superalgebra . The corresponding Bethe ansatz equations have an interesting form. We derive…
The algebraic Bethe ansatz for rational braid-monoid lattice models
M. J. Martins, P. B. Ramos
In this paper we study isotropic integrable systems based on the braid-monoid algebra. These systems constitute a large family of rational multistate vertex models and are realized…
Exact resonance A-D-E S-matrices and their renormalization group trajectories
M. J. Martins
We introduce the A-D-E resonance factorized models as an appropriate analytical continuation of the Toda S-matrices to the complex values of their coupling constant. An investigati…
Renormalization group trajectories from resonance factorized S-matrices
Marcio J. Martins
We propose and investigate a large class of models possessing resonance factorized S-matrices. The associated Casimir energy describes a rich pattern of renormalization group traje…
The two-dimensional O(3) nonlinear -model at finite temperature
Marcio J. Martins
We present a direct derivation of the thermodynamic integral equations of the O(3) nonlinear -model in two dimensions.
The thermodynamic Bethe ansatz for deformed W conformal field theories
Marcio J. Martins
We propose and investigate the thermodynamic Bethe ansatz equations for the minimal models~(associated with the Lie algebra) perturbed by the least~( invaria…
