Researchers from the University of Bonn, Heidelberg University, and the National Autonomous University of Mexico have observed critical scaling behavior in a two-dimensional photon gas approaching a phase transition. They documented how thermodynamic quantities grow extremely large or diverge as the photon gas approaches Bose-Einstein condensation, a phenomenon never previously demonstrated in photon systems. This work provides the first experimental evidence of critical scaling in photon gases near phase transitions.


This research advances fundamental understanding of quantum phase transitions and photon behavior under extreme conditions. The findings could inform development of photon-based quantum technologies and provide new experimental tools for studying critical phenomena in quantum systems.


A team of researchers from the University of Bonn, Heidelberg University and the National Autonomous University of Mexico has studied the critical behavior of light particles (photons) close to a phase transition. This critical scaling behavior, which sees thermodynamic quantities grow extremely large or diverge shortly prior to Bose-Einstein condensation, had never before been seen in photon gases until the researchers successfully secured precisely this proof.
