Interaction of the gravitational Hawking radiation and a static point mass
João P. B. Brito, Atsushi Higuchi, LuÃs C. B. Crispino
We study the interaction of a stress-energy tensor describing a static point mass supported by a string outside a Schwarzschild black hole with the gravitons of the Hawking radiati…
Proposal to use laser-accelerated electrons to probe the axion-electron coupling
Georgios Vacalis, Atsushi Higuchi, Robert Bingham +1
The axion is a hypothetical particle associated with a possible solution to the strong CP problem and is a leading candidate for dark matter. In this paper we investigate the emiss…
Larmor radiation as a witness to the Unruh effect
Atsushi Higuchi, George E. A. Matsas, Daniel A. T. Vanzella +5
We discuss the emission of radiation from general sources in quantum scalar, electromagnetic and gravitational fields using the Rindler coordinate frame, which is suitable for a un…
Multipole decomposition of the gravitational field of a point mass at the black hole horizon
João P. B. Brito, Atsushi Higuchi, LuÃs C. B. Crispino
The portion of the gravitational energy absorbed by the black hole due to the radial infall of a point mass is known to diverge at leading order in perturbation theory. This diverg…
