Bridging entanglement dynamics and chaos in semiclassical systems
It is widely recognized that entanglement generation and dynamical chaos are intimately
related in semiclassical models via the process of decoherence. In this paper, we propose a …

Entanglement entropy converges to classical entropy around periodic orbits
We consider oscillators evolving subject to a periodic driving force that dynamically
entangles them, and argue that this gives the linearized evolution around periodic orbits in a …
