Speaker: Claus Kiefer (University of Cologne)

Title: DECOHERENCE – From Schr√∂dinger’s Cat to the Classical World

How does the classical behaviour emerge in a world that is fundamentally described by quantum theory? The key to the answer is given by a process that was described for the first time forty years ago – decoherence. Decoherence is the irreversible emergence of classical properties of a quantum system through the unavoidable interaction with its environment. In my talk I shall give a general introduction into decoherence and present its most important theoretical and experimental applications. These include, in particular, the localization of objects.
I shall then discuss the relevance of decoherence for the interpretation of quantum theory and end with an outlook on quantum cosmology and the origin of the direction of time.
