Exact solution for the spin-s XXZ quantum chain with non-diagonal twists
We study integrable vertex models and quantum spin chains with toroidal boundary conditions. An interesting class of such boundaries is associated with non-diagonal twist matrices. For such models there are no trivial reference states upon which a Bethe ansatz calculation can be constructed, in contrast to the well-known case of periodic boundary conditions. In this paper we show how the transf...
متن کاملComplete 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. ...
متن کاملPath Integral Representations for the Spin-Pinned Quantum XXZ Chain
Two discrete path integral formulations for the ground state of a spinpinned quantum anisotropic XXZ Heisenberg chain are introduced. Their properties are discussed and two recursion relations are proved.

متن کاملModified Quantum Renormalization Group for xxz spin chain
A simple modification of the standard Renormalization Group (RG) technique for the study of quantum spin systems is introduced. By applying this method to the xxz spin 1 2 Heisenberg chain, we obtain the ground state energy with much higher accuracy than the standard RG.
متن کاملA Modified Quantum Renormalization Group for xxz Spin Chain
A simple modification of the standard Renormalization Group (RG) technique for the study of quantum spin systems is introduced. Our method which takes into account the effect of boundary conditions by employing the concept of superblock, may be regarded as a simple way for obtaining first estimates of many properties of spin systems. By applying this method to the xxz spin 1 2 Heisenberg chain,...
