The Multiparticle Quantum Arnol'd Cat: a test case for the decoherence approach to quantum chaos
arXiv:1007.0855
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.
