The Integrable Open Xxz Chain with Broken Z2 Symmetry
نویسنده
چکیده
The hamiltonian of an asymmetric diffusion process with injection and ejection of particles at the ends of a chain of finite length is known to be relevant to that of the spin1 2 XXZ chain with integrable boundary terms. However, the inclusion of boundary sources and sinks of particles breaks the arrow-reversal symmetry necessary for solution via the usual Bethe Ansatz approach. Developments in solving the model in the absence of arrow-reversal symmetry are discussed.

We study the phase diagram of S = 3/2 and S = 2 bond-alternating spin chains numerically. In previous papers, the phase diagram of S = 1 XXZ spin chain with bond-alternation was shown to reflect the hidden Z2 ×Z2 symmetry. But for the higher S Heisenberg spin chain, the successive dimerization transition occurs, and for anisotropic spin chains the phase structure will be more colorful than the ...
متن کاملFunctional relations and Bethe Ansatz for the XXZ chain
There is an approach due to Bazhanov and Reshetikhin for solving integrable RSOS models which consists of solving the functional relations which result from the truncation of the fusion hierarchy. We demonstrate that this is also an effective means of solving integrable vertex models. Indeed, we use this method to recover the known Bethe Ansatz solutions of both the closed and open XXZ quantum ...
متن کاملQuantum Group Uq(sl(2)) Symmetry and Explicit Evaluation of the One-Point Functions of the Integrable Spin-1 XXZ Chain
We show some symmetry relations among the correlation functions of the integrable higher-spin XXX and XXZ spin chains, where we explicitly evaluate the multiple integrals representing the one-point functions in the spin-1 case. We review the multipleintegral representations of correlation functions for the integrable higher-spin XXZ chains derived in a region of the massless regime including th...
متن کاملNon-Local Meta-Conformal Invariance, Diffusion-Limited Erosion and the XXZ Chain
Diffusion-limited erosion is a distinct universality class of fluctuating interfaces. Although its dynamical exponent z = 1, none of the known variants of conformal invariance can act as its dynamical symmetry. In d = 1 spatial dimensions, its infinite-dimensional dynamic symmetry is constructed and shown to be isomorphic to the direct sum of three loop-Virasoro algebras. The infinitesimal gene...
متن کاملCorrespondence between the XXZ model in roots of unity and the one-dimensional quantum Ising chain with different boundary conditions
We consider the integrable XXZ model with special open boundary conditions that renders its Hamiltonian SU(2)q symmetric, and the one-dimensional quantum Ising model with four different boundary conditions. We show that for each boundary condition the Ising quantum chain is exactly given by the Minimal Model of integrable lattice theory LM(3, 4). This last theory is obtained as the result of th...
