High-order gravitational late-time tails in Kerr spacetime
Marc Casals, Chris Kavanagh, Jakob Neef +1
We calculate high-order late-time tails of the retarded Green function of the Teukolsky equation for linear field perturbations of (subextremal) Kerr spacetime. We calculate these…
Quantum fluxes and for a non-minimally coupled scalar field: ringdown and tail on approaching the polar Kerr inner horizon
Maria Alberti, Noa Zilberman, Marc Casals +1
We compute as well as the energy fluxes and (where and $v…
Computation of and quantum fluxes at the polar interior of a spinning black hole
Noa Zilberman, Marc Casals, Adam Levi +2
Renormalization of physical quantities for quantum field theories in curved spacetimes can be achieved via the consistent subtraction of counterterms within a regularization scheme…
Lensing of Vacuum Entanglement near Schwarzschild Black Holes
João G. A. Caribé, Robert H. Jonsson, Marc Casals +2
An important feature of Schwarzschild spacetime is the presence of orbiting null geodesics and caustics. Their presence implies strong gravitational lensing effects for matter and…
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…
Two-point function of a quantum scalar field in the interior region of a Kerr black hole
Noa Zilberman, Marc Casals, Amos Ori +1
Quantum field effects on a classical background spacetime may be obtained from the semiclassical equations of General Relativity with the expectation value of the stress-energy ten…
