AI Summary

Researchers from the University of Bonn, Heidelberg University and the National Autonomous University of Mexico have demonstrated critical scaling in a two‑dimensional photon gas as it approaches Bose‑Einstein condensation. They observed thermodynamic quantities diverging near the phase transition, providing the first direct evidence of this behavior in photon gases. The findings confirm that light particles exhibit the same critical phenomena previously seen in other condensed‑matter systems.
