Quantum superradiance on static black hole space-times
Visakan Balakumar, Rafael P. Bernar, Luis C. B. Crispino +1
We study the quantum analogue of the classical process of superradiance for a massless charged scalar field on a static charged black hole space-time. We show that an "in" vacuum s…
Synchrotron geodesic radiation in Schwarzschild-de Sitter spacetime
João P. B. Brito, Rafael P. Bernar, Luís C. B. Crispino
We analyze the scalar radiation emitted by a source in geodesic circular orbits around a Schwarzschild-de Sitter black hole. We obtain the emitted power using quantum field theory…
Scalar radiation emitted by a source around a spherically symmetric black hole
Rafael Bernar
We analyze the scalar radiation emitted by a source in a circular geodesic orbit around a spherically symmetric black hole. The black hole spacetime considered is quite general, in…
