Uniformly accelerated classical sources as limits of Unruh-DeWitt detectors

Quantum power distribution of relativistic acceleration radiation: classical electrodynamic analogies with perfectly reflecting moving mirrors

“…That is, a globally uniformly accelerated mirror does not radiate [15] energy but does radiate particles (as is well known [37][38][39]). This is also in-line with the fact that uniformly accelerated point-like structure-less sources emit only zeroenergy Rindler particles [13].…”

“…Recent studies ( [11][12][13]) have also strengthened the connection between quantum acceleration radiation and classical radiation of point charges, namely the works by Landulfo-Fulling-Matsas who found [12] zero-energy Rindler modes are not mathematical artifacts but are critical to understanding the radiation in both the classical and quantum realm, confirming that Larmor radiation emitted by a charge can be seen as a consequence of the Unruh thermal bath. Moreover, Cozzella-Fulling-Landulfo-Matsas [13] conclude that uniformly accelerated pointlike structureless sources emit only zero-energy Rindler particles using Unruh-deWitt detectors [14]. The analogies hold true with respect to the uniformly accelerated moving mirror which emits zero energy flux but produce non-zero particle counts as computed from the beta Bogolubov coefficients (e.g.…”

Dual-temperature acceleration radiation

“…The small frequency infrared divergence demonstrates the infinite soft total particle count (some of which are zero-energy Rindler particles [24,25]) commonly associated with drifting moving mirror solutions [23,[26][27][28][29][30] (remnant analogs), that are not strictly asymptotically static [8,[31][32][33][34][35][36] (effervescent analogs).…”
