Quantum Scattering in Schwarzschild Spacetime: Hawking Radiation and Black Hole Atmospheres
Victor H. Alencar, Gabriel Picanço, Carlos A. D. Zarro
In this paper, we investigate scattering of a scalar field near a Schwarzschild black hole through its -matrix. Within this framework, we obtain a novel derivation of Hawking ra…

Black Hole Evaporation as a Topological Tunneling
Victor H. Alencar
We present the quantization of the electromagnetic field near the event horizon of a Schwarzschild black hole using Euclidean path integrals. Our result for the vacuum energy descr…
