The Marquardt group conducts research in theoretical physics, at the interface between quantum optics and nanophysics. It is affiliated with the Friedrich-Alexander University Erlangen-Nuremberg and with the Max Planck Institute for the Science of Light, both located in the city of Erlangen, in Germany. Erlangen University is the second-largest university in the federal state of Bavaria, with about 40,000 students and a full range of subjects.
The physics department identifies the light/matter interface as one of its three focal points. The Max Planck Institute is one of about 80 institutes all across Germany, and its mission is to perform cutting-edge fundamental research in modern optics.
