Calculation of a regularized Teukolsky Green function in Schwarzschild spacetime
David Q. Aruquipa, Marc Casals, Brien C. Nolan
We obtain exact expressions for various factors involved in the Hadamard form of the retarded Green function for the (Bardeen-Press-)Teukolsky equation on Schwarzschild spacetime.…
Green functions of the Regge-Wheeler and Teukolsky equations in Schwarzschild spacetime
David Q. Aruquipa, Marc Casals
We present a calculation of the full retarded Green functions of the Regge-Wheeler and Teukolsky equations obeyed by gravitational field perturbations of Schwarzschild spacetime. W…
Hadamard Tail from Initial Data on the Light Cone
David Q. Aruquipa, Marc Casals
Field perturbations of a curved background spacetime generally propagate not only at the speed of light but also at all smaller velocities. This so-called contribu…
Communication through quantum fields near a black hole
Robert H. Jonsson, David Q. Aruquipa, Marc Casals +2
We study the quantum channel between two localized first-quantized systems that communicate in 3+1 dimensional Schwarzschild spacetime via a quantum field. We analyze the informati…
Analogue gravity and radial fluid flows: The case of AdS and its deformations
David Q. Aruquipa, Ricardo A. Mosna, J. P. M. Pitelli
An analogue model for the spacetime has been recently introduced by Mosna, Pitelli and Richartz [Phys. Rev. D 94, 104065 (2016)] by considering sound waves propagati…
