A study by the University of Bonn gives novel insight into properties which are often difficult to observe
Thousands of particles of light can merge into a type of “super photon” under suitable conditions. Physicists call such a state a photon Bose-Einstein condensate. Researchers at the University of Bonn have now shown that this exotic quantum state obeys a fundamental theorem of physics. This finding now allows one to measure properties of photon Bose-Einstein condensates which are usually difficult to access. The study has been published in the journal “Nature Communications.”
