On quantum group symmetry and Bethe ansatz for the asymmetric twin spin chain with integrable boundary

Motivated by a study of the crossing symmetry of the asymmetric twin or ‘gemini’ representation of the affine Hecke algebra we give a construction for crossing tensor space representations of ordinary Hecke algebras. These representations build solutions to the Yang– Baxter equation satisfying the crossing condition (that is, integrable quantum spin chains). We show that every crossing represen...

Bethe Ansatz solution of the open XX spin chain with nondiagonal boundary terms

We consider the integrable open XX quantum spin chain with nondiagonal boundary terms. We derive an exact inversion identity, using 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 Jacobian elliptic functions.

Complete Bethe Ansatz solution of the open spin-s XXZ chain with general integrable boundary terms

We consider the open spin-s XXZ quantum spin chain with N sites and general integrable boundary terms for generic values of the bulk anisotropy parameter, and for values of the boundary parameters which satisfy a certain constraint. We derive two sets of Bethe Ansatz equations, and find numerical evidence that together they give the complete set of (2s + 1)N eigenvalues of the transfer matrix. ...

UvA - DARE ( Digital Academic Repository ) Fine structure of the Bethe Ansatz for the spin - 1 / 2 Heisenberg XXX model

We analyse the Bethe ansalz equations for the two-particle sector of the spin-; Heisenberg X X X model on a one-dimensional lattice of length N . We show that. beginning at a critical lattice length of N = 21.86. new pairs of real solutions develop, whereas complex solutions star1 to disappear. 'Ibe integers (that appear in the logarithmic form of the Bethe equations) of the o w solutions do no...

Thermodynamic Bethe ansatz equation for osp(1|2) integrable spin chain

The thermodynamic Bethe ansatz is applied to a quantum integrable spin chain associated with the Lie superalgebra osp(1|2). Using the string hypothesis, we derive a set of infinite number of non-linear integral equations (thermodynamic Bethe ansatz equation), which characterize the free energy. The low temperature limit of the free energy is also discussed. Modern Physics Letters A, in press. S...
