    "abstract": "We study dynamical generation of entanglement in bipartite quantum systems,\ncharacterized by purity (or linear entropy), and caused by the coupling between\nthe two subsystems. Explicit semiclassical theory of purity decay is derived\nfor integrable classical dynamics of the uncoupled system, and for localized\n(general Gaussian wave-packet) initial states. Purity decays as an algebraic\nfunction of time times strength of perturbation, independently of the Planck\u0027s\nconstant.",
