Vacuuminduced quantum decoherence and the entropy puzzle
Abstract
Or: "How to generate an ensemble in a single event?" Following recent work on entropy in strong interactions, I explain the concept of environmentinduced quantum decoherence in elementary quantum mechanics. The classically chaotic inverted oscillator becomes partially decoherent already in the environment of a single other oscillator performing only vacuum fluctuations. One finds exponential entropy growth in the subsystem with a Lyapunov exponent, which approaches the classical one for weak coupling. The full version of this contribution is contained in Ref. [1].
