Integrability and Conformal Symmetry in the BCS model
G. Sierra
The exactly solvable BCS Hamiltonian of superconductivity is considered from several viewpoints: Richardson's ansatz, conformal field theory, integrable inhomogenous vertex models…

New Integrable Deformations of Higher Spin Heisenberg-Ising Chains
C. Gomez, G. Sierra
We show that the anisotropic Heisenberg-Ising chains with higher spin allow, for special values of the anisotropy, integrable deformations intimately related to the theory of quant…

On a New Class of Integrable Models
A. Berkovich, C. Gomez, G. SIERRA
We define a new class of integrable vertex models associated to quantum groups at roots of unit
