Many-Body Systems and Quantum Chaos: The Multiparticle Quantum Arnol’d Cat
A multi-particle extension of the Arnol’d cat Hamiltonian system is presented, which can serve as a fully dynamical model of decoherence. The behavior of the von Neumann entropy of the reduced density matrix is studied, in time and as a function of the physical parameters, with special regard to inc...
