- Description
- We consider the Quantum Inverse Scattering Method with a new R-matrix depending on two parameters <math>q\,\!</math> and <math>t\,\!</math>. We find that the underlying algebraic structure is the two-parameter deformed algebra <math>SU_{q,t}(2)\,\!</math> enlarged by introducing an element belonging to the centre. The corresponding Hamiltonian describes the spin-1/2 XXZ model with twisted periodic boundary conditions.
