    "abstract": "Entropy generation in quantum sytems is tied to the existence of a\nnonclassical environment (heat bath or other) with which the system interacts.\nThe continuous `measuring\u0027 of the open system by its environment induces\ndecoherence of its wave function and entropy increase. Examples of\nnonrelativistic quantum Brownian motion and of interacting scalar fields\nillustrate these general concepts. It is shown that the Hartree-Fock\napproximation around the bare classical limit can lead to spurious semiquantum\nchaos, which may affect the determination of entropy production and\nthermalization also in other cases.",
