This book treats modern aspects of open systems, measurement & decoherence in relativistic quantum theory. It starts with a comprehensive introduction to the problems related to measuring local & nonlocal observables & the constraints imposed by the causality principle. In the articles that follow, the emphasis lies on new theoretical models. Quantum dynamical semigroups & stochastic processes in Hilbert space are introduced, as are dynamical reduction models. Further topics include relativistic generalizations of the continuous spontaneous localization model & of the quantum state diffusion model & decoherence & the dynamical selection of preferred basis sets in the framework of continuous measurement theory & of the decoherent histories approach. Mathematical aspects of quantum measurement theory & dynamical entropies are also studied from the viewpoint of the operational approach to quantum mechanics.
