Dynamical Criterion for Quantum Chaos: Entropy Production in Subsystems

Quantum Physics 2007-05-23 v2

Abstract

We examine the conjecture that entropy production in subsystems of a given system can be used as a dynamical criterion for quantum chaos in the latter. Numerical results are presented for finite dimensional spin systems as also for the quantum baker's map. Of especial importance is the power spectrum of the entropy production which gets progressively more and more broad-banded as the degree of correlation in the Hamiltonian matrix is made to decrease.
