The Multiparticle Quantum Arnol'd Cat: a test case for the decoherence approach to quantum chaos (1007.0855v1)
Published 6 Jul 2010 in quant-ph, cond-mat.stat-mech, math-ph, math.MP, and nlin.CD
Abstract: A multi-particle extension of the Arnol'd Cat Hamiltonian system is defined and examined. We propose to compute its Alicki-Fannes quantum dynamical entropy, to validate (or disprove) the validity of the decoherence approach to quantum chaos. A first set of numerical experiments is presented and discussed.
