1204.3614 (I. Garcia-Mata et al.)

Non-Markovian Quantum Dynamics and Classical Chaos    [PDF]

I. Garcia-Mata, C. Pineda, D. A. Wisniacki
We study the influence of a chaotic environment in the evolution of an open quantum system. We show that there is an inverse relation between chaos and non-Markovianity. In particular we remark the deep relation of the short time non-Markovian behavior with the revivals of the average fidelity amplitude -- a fundamental quantity used to measure sensitivity to perturbations, and identify quantum chaos. The long time behavior is established as a finite size effect which vanishes for large enough environments.
