Decoherence of Interacting Quantum Oscillators and Quantum Synchronization — •Björn Bartels — Freiburg Institute for Advanced Studies, Albert-Ludwigs-Universität Freiburg, Albertstr. 19, 79104 Freiburg, Germany — Institut für Theoretische Physik, Universität Würzburg, 97074 Würzburg, Germany

Decoherence is responsible for the absence of quantum mechanical effects in our everyday life. In particular, in macroscopic systems there is a preferred direction of time, whereas quantum mechanics is invariant under time reversal. In classical mechanics, two coupled dissipative oscillators evolving into a synchronized state represent a typical example of an irreversible process. In this talk, we consider the quantum dynamics of two interacting harmonic oscillators coupled to a bosonic heat bath, in order to investigate the possibility of synchronization in quantum systems without loss of their non-classicality.
