WebDec 1, 2024 · In this paper, it is shown that the Hamiltonian of the open spin-1 XXZ chain model can be constructed from the generators of the Birman–Murakami–Wenzl (B–M–W) algebra. Without the ... A spin chain is a type of model in statistical physics. Spin chains were originally formulated to model magnetic systems, which typically consist of particles with magnetic spin located at fixed sites on a lattice. A prototypical example is the quantum Heisenberg model. Interactions between the sites are … See more The most prominent example of a spin chain is the Heisenberg spin chain, described by Werner Heisenberg in 1928.

WebMay 26, 2024 · The XXZ spin chain is an integrable generalization of the Heisenberg chain that accounts for a uni-axial anisotropy in the spin interaction. WebFeb 11, 2014 · We study spin chains submitted to disturbed kick trains described by classical dynamical processes. The spin chains are described by Heisenberg and Ising models. We consider decoherence, entanglement, relaxation and chaotic processes induced by the kick irregularity in the multipartite system (the spin chain). We show that the … WebMay 20, 2013 · We provide an introduction to this subject by focusing on the time evolution of a Heisenberg spin-1/2 chain and interpreting the results based on the analysis of the … the humma song
