Daqing Wang received his PhD from the Max-Planck Institute for the Science of Light and the University of Erlangen-Nuremberg in 2019. His PhD thesis on cavity-quantum electrodynamics with single molecules was awarded the Dissertation Prize of the German Physical Society (DPG) in 2020. After his PhD, he was a postdoctoral researcher and junior Principal Investigator at the University of Kassel. In the year 2022, he was awarded a Starting Grant by the European Research Council (ERC). Since October 2023, he is a tenure-track-professor at the University of Bonn.

Abstract

Molecules are ubiquitous in nature and play a crucial role in physics, chemistry, and biology. Experimental masteries of light-molecule interactions at the quantum level provide not only a platform for investigating questions fundamental to quantum mechanics, but also new possibilities to develop building blocks for a quantum network. In this presentation, I will give an overview of our research activities focused on studying light-molecule interactions at the level of single molecules and single photons. In the first part, I will present an experiment aimed at performing precise measurements on chiral molecules through the action of optical forces. In the second part, I will review our activities in developing quantum light-matter interfaces based on single dye molecules in the solid state.
