Integrability of the Heisenberg Chains with Boundary Impurities and Their Bethe Ansatz
نویسندگان
چکیده
In this paper, we show the integrability of spin-1/2 XXZ Heisenberg chain with two arbitrary spin boundary Impurities. By using the fusion method, we generalize it to the spin-1 XXZ chain. Then the eigenvalues of Hamiltonians of these models are obtained by the means of Bethe ansatz method. Pacs: 75.20H, 12.40E, 75.10D

The matrix product ansatz for the six - vertex model
Recently it was shown that the eigenfunctions for the the asymmetric exclusion problem and several of its generalizations as well as a huge family of quantum chains, like the anisotropic Heisenberg model, Fateev-Zamolodchikov model, Izergin-Korepin model, Sutherland model, t − J model, Hubbard model, etc, can be expressed by a matrix product ansatz. Differently from the coordinate Bethe ansatz,...
متن کاملIntegrable open boundary conditions for the Bariev model of three coupled XY spin chains
The integrable open-boundary conditions for the Bariev model of three coupled one-dimensional XY spin chains are studied in the framework of the boundary quantum inverse scattering method. Three kinds of diagonal boundary K-matrices leading to nine classes of possible choices of boundary fields are found and the corresponding integrable boundary terms are presented explicitly. The boundary Hami...
متن کاملUq(glN ) quantum spin chains
The glN and Uq(glN ) quantum spin chains in the presence of integrable spin impurities are considered. Within the Bethe ansatz formulation, we derive the associated transmission amplitudes, and the corresponding transmission matrices –representations of the underlying quadratic algebra– that physically describe the interaction between the various particle-like excitations displayed by these mod...
متن کاملINTEGRABILITY OF A t− J MODEL WITH IMPURITIES
A t− J model for correlated electrons with impurities is proposed. The impurities are introduced in such a way that integrability of the model in one dimension is not violated. The algebraic Bethe ansatz solution of the model is also given and it is shown that the Bethe states are highest weight states with respect to the supersymmetry algebra gl(2|1).

متن کاملReview of AdS/CFT Integrability, Chapter III.1: Bethe Ansätze and the R-Matrix Formalism
The one-dimensional Heisenberg XXX spin chain appears in a special limit of the AdS/CFT integrable system. We review various ways of proving its integrability, and discuss the associated methods of solution. In particular, we outline the coordinate and the algebraic Bethe ansatz, giving reference to literature suitable for learning these techniques. Finally, we speculate which of the methods mi...
