Tiny circuits mimic spinning black holes

Researchers at the City University of New York have achieved the first experimental demonstration of rotational super-radiance using electromagnetic waves. By utilizing a stationary circuit of resonators that mimics rapid rotation through timing shifts, the team bypassed the physical impossibility of spinning an object fast enough to amplify light.
