Integrable 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 کاملHirota Equation and Bethe Ansatz
The paper is a review of recent works devoted to analysis of classical integrable structures in quantum integrable models solved by one or another version of the Bethe ansatz. Similarities between elements of the quantum and classical theories of integrable systems are discussed. Some key notions of the quantum theory, now standard in the quantum inverse scattering method, are identiied with ty...
متن کاملThe Asymmetric Simple Exclusion Process : An Integrable Model for Non-Equilibrium Statistical Mechanics
The Asymmetric Simple Exclusion Process (ASEP) plays the role of a paradigm in NonEquilibrium Statistical Mechanics. We review exact results for the ASEP obtained by Bethe Ansatz and put emphasis on the algebraic properties of this model. The Bethe equations for the eigenvalues of the Markov Matrix of the ASEP are derived from the algebraic Bethe Ansatz. Using these equations we explain how to ...
متن کاملThermodynamic 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...
متن کامل“New” boundary conditions in integrable lattice models
We consider the case of an integrable quantum spin chain with “soliton non-preserving” boundary conditions. This is the first time that such boundary conditions have been considered in the spin chain framework. We construct the transfer matrix of the model, we study its symmetry and we find explicit expressions for its eigenvalues. Moreover, we derive a new set of Bethe ansatz equations by mean...
