Superradiance -- the 2020 Edition

Paolo Pani, Richard Brito, Vitor Cardoso

Black-hole superradiance extracts energy, charge and angular momentum from rotating black holes and triggers instabilities when the radiation is confined.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Black-hole superradiance is intimately connected to the black-hole area theorem, Penrose process, tidal forces, and even Hawking radiation, which can be interpreted as a quantum version of black-hole superradiance. Various mechanisms can confine the amplified radiation and give rise to strong instabilities with applications in searches of dark matter and physics beyond the Standard Model.

C2weakest assumption

The assumption that confining mechanisms (massive fields, magnetic fields, AdS boundaries, nonlinear interactions) exist in realistic astrophysical or laboratory settings and produce observable instabilities without being quenched by other effects.

C3one line summary

Black-hole superradiance extracts energy via the ergoregion and can trigger instabilities with applications to dark matter, beyond-Standard-Model physics, and laboratory analogs.
