Quantum entropy dynamics for chaotic systems beyond the classical limit

The entropy production rate for an open quantum system with a classically chaotic limit has been previously argued to be independent of h and D, the parameter denoting coupling to the environment, and to be equal to the sum of generalized Lyapunov exponents, with these results applying in the near-c...

Summary:The entropy production rate for an open quantum system with a classically chaotic limit has been previously argued to be independent of h and D, the parameter denoting coupling to the environment, and to be equal to the sum of generalized Lyapunov exponents, with these results applying in the near-classical regime. We present results for a specific system going well beyond earlier work, considering how these dynamics are altered for the Duffing problem by changing h,D and show that the entropy dynamics have a transition from classical to quantum behavior that scales, at least for a finite time, as a function of h2/D.
