Claude Cohen-Tannoudji

Claude Cohen-Tannoudji is a French physicist affiliated with Collège de France and École normale supérieure. He is renowned for his work in quantum mechanics, laser cooling, and atom-photon interactions, culminating in the 1997 Nobel Prize in Physics shared with Steven Chu and William Daniel Phillips.

• Alma mater: École normale supérieure, University of Paris
• Doctoral advisor: Alfred Kastler

Research interests span quantum optics, atomic physics, and statistical approaches to laser cooling. He pioneered the dressed atom model and applied Lévy statistics to non-ergodic cooling phenomena.

Scientific awards include the Nobel Prize in Physics (1997), CNRS Gold Medal (1996), and Legion of Honour (2010). Notable contributions to quantum mechanics textbooks and leadership in climate change advocacy via the 2015 Mainau Declaration further highlight his career.

• Doctoral students:
  • Serge Haroche
  • Jean Dalibard
  • Claude Fabre

Labs and teams include collaborations with Alain Aspect, Christophe Salomon, and Jean Dalibard at Collège de France, advancing laser cooling and trapping technologies.
