Phys.org  October 7, 2021 Researchers in the Netherlands investigated the Bose-Einstein condensation of a photonic Bose gas in an environment with controlled dissipation and feedback. They created a micro-size mirror with channels in which photons flow like a liquid. They showed that by adjusting their frequency Bose-Einstein condensates naturally try to avoid particle loss and destructive interference in their environment. Their experiments revealed physical mechanisms involved in the formation of a Bose-Einstein condensate, which typically remain hidden when the system is close to thermal equilibrium. They demonstrated the effect even at room temperature. Their measurements offer a highly systematic picture […]
