Gravity-induced transparency
arXiv:2406.01227 · doi:10.1103/PhysRevD.109.125018
Abstract
We investigate the transition amplitudes of the Unruh-DeWitt detector within the Schwarzschild spacetime background and discover gravity-induced transparency phenomena akin to the earlier acceleration-induced transparency. This is confirmed through calculations performed in both the Hartle-Hawking and Unruh states. The similarity between free-falling detectors in these states and accelerated detectors in electromagnetic fields is noteworthy, as it parallels the scenario in which acceleration-induced transparency phenomena occur.
