Superreflection and quantum particle production
Abstract
Reflection and amplification with phase velocity exceeding the speed of light are considered for the case of rotatory motion of an axisymmetric body interacting with incident radiation with a wave of assigned multipolarity. The study is extended from superreflection on a rotating conducting cylinder to superreflection from a rotating black hole. An EM wave generator based on the phenomenon is considered. The quantum mechanical analog of the effect is identified as spontaneous production of particle pairs by a rotating body. Quantum pair production in a gravitational field governed by a Kerr metric (black hole case) is discussed.
