Why Physicists Just Filmed Quantum Tornadoes Swirling Inside a Solid Crystal
At a temperature of 15 nanokelvin—less than one-billionth of a degree above absolute zero—an ensemble of approximately 50,000 dysprosium-164 atoms was forced to rotate at 50 revolutions per second inside a vacuum chamber in Innsbruck, Austria. The resulting images revealed singular empty channels, e ...
