Abstract

We propose a generalization of the Baxter T – Q relation which involves more than one independent Q ( u ). We argue that the eigenvalues of the transfer matrix of the open XXZ quantum spin chain are given by such generalized T – Q relations, for the case that at most two of the boundary parameters {α − , α + , β − , β + } are nonzero, and the bulk anisotropy parameter has values η = iπ/2, iπ/4, ....

GeneralizedT–Qrelations and the open spin-sXXZ chain with nondiagonal boundary terms

Rashad Baiyasi, Rajan Murgan

We consider the open spin- s XXZ quantum spin chain with nondiagonal boundary terms. By exploiting certain functional relations at roots of unity, we derive a generalized form of T – Q relation involving more than one independent Q ( u ), which we use to propose the Bethe-ansatz-type expressions for the eigenvalues of the transfer matrix. At most two of the boundary parameters are set to be arbitrary and the bulk anisotropy parameter has values η = iπ/2,iπ/4,.... We also provide numerical evidence for the completeness of the Bethe-ansatz-type solutions derived, using the s = 1 case as an example.

The transfer matrix of the general integrable open XXZ quantum spin chain obeys certain functional relations at roots of unity. By exploiting these functional relations, we determine the Bethe Ansatz solution for the transfer matrix eigenvalues for the special cases that all but one of the boundary parameters are zero, and the bulk anisotropy parameter is i\\pi/3, i\\pi/5 ,...

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.

Exact solution of the open XXZ chain with general integrable boundary terms at roots of unity

Rajan Murgan, Rafael I. Nepomechie, Chi Shi

We propose a Bethe-ansatz-type solution of the open spin-1/2 integrable XXZ quantum spin chain with general integrable boundary terms and bulk anisotropy values iπ/( p +1), where p is a positive integer. All six boundary parameters are arbitrary, and need not satisfy any constraint. The solution is in terms of generalized T – Q equations, having more than one Q function. We find numerical evidence that this solution gives the complete set of 2 N transfer matrix eigenvalues, where N is the number of spins.
