Non-diagonal reflection for the non-critical XXZ model
نویسنده
چکیده
The most general physical boundary S-matrix for the open XXZ spin chain in the non-critical regime (cosh(η) > 1) is derived starting from the bare Bethe ansazt equations. The boundary S-matrix as expected is expressed in terms of Γq-functions. In the isotropic limit corresponding results for the open XXX chain are also reproduced. e-mail: [email protected]

Functional relations from the Yang-Baxter algebra: Eigenvalues of the XXZ model with non-diagonal twisted and open boundary conditions
In this work we consider a functional method in the theory of exactly solvable models based on the Yang-Baxter algebra. Using this method we derive the eigenvalues of the XXZ model with non-diagonal twisted and open boundary conditions for general values of the anisotropy and boundary parameters. PACS numbers: 05.50+q, 02.30.IK
متن کاملBoundary quantum group generators from the open transfer matrix
We present a systematic way of constructing boundary quantum group generators associated to non-diagonal solutions of the reflection equation for the XXZ model. This is achieved by studying the asymptotics of the corresponding open transfer matrix. Linear intertwining relations for the K matrix and Sklyanin’s operator are also obtained, and the symmetry of the transfer matrix is investigated. L...
متن کاملSimulations of Quantum XXZ Models on Two-Dimensional Frustrated Lattices
We report recent progress in the study of a particular class of spin 1/2 XXZ model on two-dimensional lattices with frustrated diagonal and unfrustrated off-diagonal interactions. Quantum Monte Carlo simulations can be constructed without a sign problem, however they require non-trivial algorithmic advances in order to combat freezing tendencies. We discuss results obtained using these techniqu...
متن کاملThe open XXZ and associated models at q root of unity
The generalized open XXZ model at q root of unity is considered. We review how associated models, such as the q harmonic oscillator, and the lattice sine-Gordon and Liouville models are obtained. Explicit expressions of the local Hamiltonian of the spin 1 2 XXZ spin chain coupled to dynamical degrees of freedom at the one end of the chain are provided. Furthermore, the boundary non-local charge...
متن کاملStructure of the two-boundary XXZ model with non-diagonal boundary terms
We study the integrable XXZ model with general non-diagonal boundary terms at both ends. The Hamiltonian is considered in terms of a two boundary extension of the Temperley-Lieb algebra. We use a basis that diagonalizes a conserved charge in the one-boundary case. The action of the second boundary generator on this space is computed. For the L-site chain and generic values of the parameters we ...
