Ansatz de Bethe para cadeias quânticas de spin-1 com condições de contorno
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2002-03-21)
The procedure for obtaining integrable open spin chain Hamiltonians via reflection
matrices explicitly carried out for some three-state vertex models. We have considered
the 19-vertex models of Zamolodchikov-Fateev and ...
A equação de Yang-Baxter para modelos de vértices com três estados
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2011-03-02)
In this work we study the solutions of the Yang-Baxter equation associated to nineteen vertex models invariant by the parity-time symmetry from the perspective of algebraic geometry. We determine the form of the algebraic ...
