Yang-Baxter Equation in Spin Chains with Long Range Interactions
نویسنده
چکیده
We consider the su(n) spin chains with long range interactions and the spin generalization of the Calogero-Sutherland models. We show that their properties derive from a transfer matrix obeying the Yang-Baxter equation. We obtain the expression of the conserved quantities and we diagonalise them. 01/93 1 Laboratoire de la Direction de Sciences de la Matière du Commissariat à l’énergie atomique.

Quasi-classical descendants of disordered vertex models with boundaries
We study descendants of inhomogeneous vertex models with boundary reflections when the spin-spin scattering is assumed to be quasi–classical. This corresponds to consider certain power expansion of the boundary-Yang-Baxter equation (or reflection equation). As final product, integrable su(2)-spin chains interacting with a long range with XXZ anisotropy are obtained. The spin-spin couplings are ...
متن کاملHecke algebraic approach to the reflection equation for spin chains
We use the structural similarity of certain Coxeter Artin Systems to the Yang–Baxter and Reflection Equations to convert representations of these systems into new solutions of the Reflection Equation. We construct certain Bethe ansatz states for these solutions, using a parameterisation suggested by abstract representation theory.
متن کاملReflection K-Matrices of the 19-Vertex Model and XXZ Spin-1 Chain with General Boundary Terms
We derive and classify all solutions of the boundary Yang-Baxter equation (or the reflection equation) for the 19-vertex model associated with Uq(ŝl2). Integrable XXZ spin-1 chain hamiltonian with general boundary interactions is also obtained.
متن کاملLong-Range Interaction Models and Yangian Symmetry
The generalized Sutherland-Römer model and Yan models with internal spin degree are formulated in terms of both the Polychronakos’ approach and RTT relation associated to Yang-Baxter equation in consistent way. The Yangian symmetry is shown to generate both the models. We finally introduce the reflection algebra K(u) to long range interaction models. PACS numbers: 05.30.-d, 03.65.Fd, 05.50.+q
متن کاملBaxter Equation for Long-range Sl(2|1) Magnet
We construct a long-range Baxter equation encoding anomalous dimensions of composite operators in the SL(2|1) sector of N = 4 supersymmetric Yang-Mills theory. The formalism is based on the analytical Bethe Ansatz. We compare predictions of the Baxter equations for short operators with available multiloop perturbative calculations.
