Cavity Quantum Electrodynamics

Cavity Quantum E-Dyn.

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 Cavity Cooling, Self-Organization, Quantum Thermodynamics, Light Forces, Superradiant Lasing and Quantum Metrology.
