CQED Theory

Welcome to Helmut Ritsch's CQED group!

Based in Innsbruck, Austria in midst of the beautiful Tyrolean alps, Helmut Ritsch's theory group has been working on Quantum Optics and Cavity Quantum Electro­dynamics since 1993. In essence, our work contributes to a better under­standing of the interaction between light and matter. Our main research interests are Self-Organization, Cavity Cooling, Superradiant Lasing and Quantum Metrology.

Apr 2019: How do Theoretical Physicists work?

We made a little public outreach video showing the everyday life of a theoretical physicist.

Our research covers the fields of quantum optics and ultracold gas physics.

Research topics

Active research in our group is conducted on Cavity Cooling, Self-Organization, Light Forces, Superradiant Lasing and Quantum Metrology, Quantum Thermodynamics as well as developing an in-house framework for numerical simulations.
