The Quantum Algebraic Structure of the Twisted XXZ Chain

High Energy Physics - Theory 2009-10-28 v2 Condensed Matter

Abstract

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