Zusammenfassung der Projektergebnisse

In this project and related work, an abrupt and synchronized transition from a quantum to the classical regime was found for a driven waveguide that is ultra-strongly coupled to multiple emitters. Furthermore we were able to calculate correlations of the signal mode in an optical parametric oscillator at threshold with a novel degree of precision using the self-consisten Mori projector approach we had developed previously. Finally we explored the potential of strong electro-nano-mechanical three-body interaction for the generation of non-classical states of the mechanical motion.
