Entropy production, dynamical localization and criteria for quantum chaos in the open quantum kicked rotor
Paul A. Miller, Sarben Sarkar
The von Neumann entropy production for a quantum mechanical kicked rotor coupled to a thermal environment is calculated. This rate of entropy increase is shown to be a good criteri…

Fingerprints of Classical Instability in Open Quantum Dynamics
Paul A. Miller, Sarben Sarkar
The dynamics near a hyperbolic point in phase space is modelled by an inverted harmonic oscillator. We investigate the effect of the classical instability on the open quantum dynam…
