FAST TRACK COMMUNICATION: Quantum dynamics and breakdown of classical realism in nonlinear oscillators
Abstract
The leading nonclassical term in the quantum dynamics of nonlinear oscillators is calculated in the Moyal quasitrajectory representation. The irreducibility of the quantum dynamics to phasespace trajectories is quantified by the discrepancy of the canonical quasiflow and the quasiflow of a general observable. This discrepancy is shown to imply the breakdown of classical realism that can give rise to a dynamical violation of Bell's inequalities.
