Quantum Entropies and Decoherence for the Multiparticle Quantum Arnol'd Cat
Giorgio Mantica
I study the scaling behavior in the physical parameters of dynamical entropies, classical and quantum, in a specifically devised model of collision-induced decoherence in a chaotic…

Behavior of correlation functions in the dynamics of the Multiparticle Quantum Arnol'd Cat
Giorgio Mantica
The multi-particle Arnol'd cat is a generalization of the Hamiltonian system, both classical and quantum, whose period evolution operator is the renown map that bears its name. It…

The Multiparticle Quantum Arnol'd Cat: a test case for the decoherence approach to quantum chaos
Giorgio Mantica
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 disprov…
