A brief history of hidden quantum symmetries in Conformal Field Theories
Cesar Gomez, German Sierra
We review briefly a stream of ideas concerning the role of quantum groups as hidden symmetries in conformal field theories, paying particular attention to the field theoretical rep…

q--Magnetism at roots of unity
A. Berkovich, G. Sierra, C. Gomez
We study the thermodynamic properties of a family of integrable 1D spin chain hamiltonians associated with quantum groups at roots of unity. These hamiltonians depend for each prim…

On Integrable Quantum Group Invariant Antiferromagnets
R. Cuerno, G. Sierra, C. Gomez
A new open spin chain hamiltonian is introduced. It is both integrable (Sklyanin`s type matrices are used to achieve this) and invariant under transformatio…
