Abstract

We compute by means of the Bethe ansatz the boundary S -matrix for the open anisotropic spin- chain with diagonal boundary magnetic fields in the noncritical regime . Our result, which is formulated in terms of q -gamma functions, agrees with the vertex-operator result of Jimbo et al .

Non-diagonal reflection for the non-criticalXXZmodel

Anastasia Doikou

The most general physical boundary $S$-matrix for the open XXZ spin chain in the non-critical regime ($\cosh (η)>1$) is derived starting from the bare Bethe ansazt equations. The boundary $S$-matrix as expected is expressed in terms of $Γ_q$-functions. In the isotropic limit corresponding results for the open XXX chain are also reproduced.

Bethe Ansatz and boundary energy of the open spin-1/2 XXZ chain

Rajan Murgan

We review recent results on the Bethe Ansatz solutions for the eigenvalues of the transfer matrix of an integrable open XXZ quantum spin chain using functional relations which the transfer matrix obeys at roots of unity. First, we consider a case where at most two of the boundary parameters {{$\\alpha_-$,$\\alpha_+$,$\\beta_-$,$\\beta_+$}} are nonzero. A generalization of the Baxter $T-Q$ equation that involves more than one independent $Q$ is described. We use this solution to compute the boundary energy of the chain in the thermodynamic limit. We conclude the paper with a review of some results for the general integrable boundary terms, where all six boundary parameters are arbitrary.

Direct calculation of breatherSmatrices

Anastasia Doikou, Rafael I Nepomechie

We formulate a systematic Bethe ansatz approach for computing bound-state (`breather') S matrices for integrable quantum spin chains. We use this approach to calculate the breather boundary S matrix for the open XXZ spin chain with diagonal boundary fields. We also compute the soliton boundary S matrix in the critical regime.

Bethe ansatz solution of the openXXspin chain with non-diagonal boundary terms

Rafael I. Nepomechie

We consider the integrable open XX quantum spin chain with non-diagonal boundary terms. We derive an exact inversion identity, by which we obtain the eigenvalues of the transfer matrix and the Bethe ansatz equations. For generic values of the boundary parameters, the Bethe ansatz solution is formulated in terms of the Jacobian elliptic functions.

Direct calculation of the boundary S-matrix for the open Heisenberg chain

M.T. Grisaru, L Mezincescu, R I Nepomechie

We calculate the boundary S-matrix for the open antiferromagnetic spin- 1/2 isotropic Heisenberg chain with boundary magnetic fields. Our approach, which starts from the model's Bethe-ansatz solution, is an extension of the Korepin-Andrei-Destri method. Our result agrees with the boundary S-matrix for the boundary sine-Gordon model with beta 2 to 8 pi and with 'fixed' boundary conditions.

Bethe ansatz solution of the open XXZ chain with nondiagonal boundary terms

Rafael I. Nepomechie

We propose a set of conventional Bethe ansatz equations and a corresponding expression for the eigenvalues of the transfer matrix for the open spin- XXZ quantum spin chain with nondiagonal boundary terms, provided that the boundary parameters obey a certain linear relation.
