Reflection K-Matrices of the 19-Vertex Model and XXZ Spin-1 Chain with General Boundary Terms

Takeo Inami, Satoru Odake, Yao-Zhong Zhang

Published Jan 1, 1996• 27 citations

Abstract

We derive and classify all solutions of the boundary Yang-Baxter equation (or the reflection equation) for the 19-vertex model associated with U_q(\widehat{sl_2}). Integrable XXZ spin-1 chain hamiltonian with general boundary interactions is also obtained.

Boundary K-matrices for the XYZ, XXZ AND XXX spin chains

Hector J. de Vega, A. González-Ruiz

The general solutions for the factorization equations of the reflection matrices $K^{\\pm}(\\theta)$ for the eight vertex and six vertex models (XYZ, XXZ and XXX chains) are found. The associated integrable magnetic Hamiltonians are explicitly derived, finding families dependig on several continuous as well as discrete parameters.

Integrable XYZ spin chain with boundaries

T. Inami, Hitoshi Konno

We consider a general class of boundary terms of the open XYZ spin-1/2 chain compatible with integrability. We have obtained the general elliptic solution of a K-matrix obeying the boundary Yang-Baxter equation using the R-matrix of the eight-vertex model and derived the associated integrable spin-chain Hamiltonian.

A Q-Operator for Open Spin Chains II: Boundary Factorization

Alec Cooper, Bart Vlaar, Robert Weston

Abstract One of the features of Baxter’s Q-operators for many closed spin chain models is that all transfer matrices arise as products of two Q-operators with shifts in the spectral parameter. In the representation-theoretical approach to Q-operators, underlying this is a factorization formula for L-operators (solutions of the Yang–Baxter equation associated to particular infinite-dimensional representations). To extend such a formalism to open spin chains, one needs a factorization identity for solutions of the reflection equation (boundary Yang–Baxter equation) associated to these representations. In the case of quantum affine $$\mathfrak {sl}_2$$ sl 2 and diagonal K-matrices, we derive such an identity using the recently formulated theory of universal K-matrices for quantum affine algebras.

We investigate the possible regular solutions of the boundary Yang–Baxter equation for the vertex models associated with the graded version of the A n −1 (1) affine Lie algebra, the U q [ sl ( m | n ) (1) ] vertex model, also known as the Perk–Schultz model.
