چکیده
We investigate a solvable SU(3)-XXZ-model modiied by elements of the Cartan-subalgebra. The nested Bethe-Ansatz is discussed in detail and the corresponding quantum spin model is stated. The coupled Bethe-equations are solved in the ther-modynamic limit. EEects of the modiication on the nite size scaling are derived.

Bethe Ansatz Equations of XXZ Model and q-Sturm-Liouville Problems
In this article we have discovered a close relationship between the (algebraic) Bethe Ansatz equations of the spin s XXZ model of a finite size and the q-Sturm-Liouville problem. We have demonstrated that solutions of the Bethe Ansatz equations give rise to the polynomial solutions of a second order q-difference equation in terms of Askey-Wilson operator. The more general form of Bethe Ansatz e...
متن کاملExact solution of the XXZ Gaudin model with generic open boundaries
The XXZ Gaudin model with generic integerable boundaries specified by generic non-diagonal K-matrices is studied. The commuting families of Gaudin operators are diagonalized by the algebraic Bethe ansatz method. The eigenvalues and the corresponding Bethe ansatz equations are obtained.

متن کاملSingularities in the Bethe solution of the XXX and XXZ Heisenberg spin chains
We examine the question of whether Bethe’s ansatz reproduces all states in the periodic Heisenberg XXZ and XXX spin chains. As was known to Bethe himself, there are states for which the Bethe momenta kn diverge: these are in fact the simplest examples of “string” solutions. The coefficients of the Bethe wavefunction, too, diverge. When there are only two down spins in the system (the case consi...
متن کاملRegular XXZ Bethe states at roots of unity – as highest weight vectors of the sl 2 loop
We show that every regular Bethe ansatz eigenstate of the XXZ spin chain at roots of unity is a highest weight vector of the sl2 loop algebra and discuss whether it generates an irreducible representation or not. We show it in some sectors with respect to eigenvalues of the total spin operator SZ . The parameter q is given by a root of unity, q2N 0 = 1, for an integer N . Here, q is related to ...
متن کاملBethe Ansatz solution of the open XXZ chain with nondiagonal boundary terms
We propose a set of conventional Bethe Ansatz equations and a corresponding expression for the eigenvalues of the transfer matrix for the open spin2 XXZ quantum spin chain with nondiagonal boundary terms, provided that the boundary parameters obey a certain linear relation.
