Bethe equations for the critical three-state Potts spin chain with toroidal boundary conditions
M. J. Martins
In this paper, we consider the parameterization of the spectra of the three-state critical Potts quantum chain with integrable twisted boundary conditions in terms of Bethe ansatz…

On the equivalence between n-state spin and vertex models on the square lattice
M. J. Martins
In this paper we investigate a correspondence among spin and vertex models with the same number of local states on the square lattice with toroidal boundary conditions. We argue th…

Embedding integrable spin models in solvable vertex models on the square lattice
M. J. Martins
Exploring a mapping among -state spin and vertex models on the square lattice we argue that a given integrable spin model with edge weights satisfying the rapidity difference pr…
