Quantum optics with organic molecules: cavity QED, optomechanics, and cooperativity
Prof. Vahid Sandoghdar (Max-Planck-Institut für die Physik des Lichts, Erlangen)

Laboratory manipulation of single quantum emitters and single photons has matured to a routine procedure over the past two decades. These activities have led to new emerging topics such as optomechanical functionalities and coherent cooperative interactions among several quantum emitters. In this presentation, I discuss our efforts of the last decade in coupling molecules to high-finesse Fabry-Perot cavities and nanoscopic waveguides on a chip, demonstrating dipole-induced transparency, strong coupling and single-photon nonlinearity. Moreover, I present data on precision spectroscopy of the vibronic transitions in single molecules as well as theoretical conception of hybrid optomechanical platforms for achieving long coherence and storage times. I will also present the latest results on the coupling of two or molecules to each other via a common mode of a micro-resonator.
