The spinning Kerr-black-hole-mirror bomb: A lower bound on the radius of the reflecting mirror
The intriguing superradiant amplification phenomenon allows an orbiting scalar field to extract rotational energy from a spinning Kerr black hole. Interestingly, the energy extraction rate can grow exponentially in time if the black-hole-field system is placed inside a reflecting mirror which preven...
