How to Cool Light to Quantum Order ⚡ экспресс
Original: "Stimulated cooling in non-equilibrium Bose-Einstein condensate"
Physicists cooled a quantum mix of light and matter to 20 degrees above absolute zero and witnessed the moment when chaos gives way to a synchronized dance.

A cloud of light and matter was cooled to near absolute zero and split into two quantum fractions with different temperatures. The effect is like bubbles of steam appearing in a pot, but at the quantum level. This condensate could become the basis for supersensitive sensors and new quantum devices.
🎯 Polaritons are billions of times lighter than atoms, so cooling them takes just moments even at temperatures relatively 'high' for the quantum world.
