Title: Entanglement dynamics for two interacting spins
Author: Novaes, M
Abstract: We study the dynamical generation of entanglement for a very simple system: a pair of interacting spins, s(1) and s(2), in a constant magnetic field. Two different situations are considered: (a) s(1) -> infinity, s(2) = 1/2 and (b) s(1) = s(2) -> infinity, corresponding, respectively, to a quantum degree of freedom coupled to a semiclassical one (a qubit in contact with an environment) and a fully semiclassical system, which in this case displays chaotic behavior. Relations between quantum entanglement and classical dynamics are investigated. (c) 2005 Elsevier Inc. All rights reserved.
