Hawking-Unruh radiation as irreversible consequence of radiative action in dynamics

TL;DR

This paper demonstrates that Hawking-Unruh radiation arises as an irreversible consequence of radiative damping effects in non-inertial frames, linking thermal phenomena to nonstationary dynamics across scales.

Contribution

It introduces a novel interpretation of Hawking-Unruh radiation as an irreversible effect caused by radiative damping in accelerated systems, extending its relevance beyond black hole physics.

Findings

Hawking-Unruh radiation is a marker of nonstationary evolution.

Recoil damping leads to thermal power similar to Hawking-Unruh radiation.

H-U effects are universal markers of decoherence across scales.

Abstract

Hawking-Unruh thermal state of warm surrounding field encountered in non-inertial frames is shown to be a real phenomenon, a marker of nonstationary dynamic evolutions. In accelerated motion of a charged particle it is shown that the recoiled damping effect of Larmor radiation relaxation leads to distinctive thermal power, which is akin to that of Hawking-Unruh radiation from warm surrounding field of the accelerated charge. The damping effect from recoil-momentum of transverse electromagnetic field is worked out by considering torque imparted to the inherently existing angular evolution of spherically polarized vacuum field around the point-like charged particle in acceleration. Hawking-Unruh effects is generally noted to be a universal marker of decoherence in evolution in all scales of microscopic, macroscopic and megascopic systems. Besides detailing the case of electrodynamics, the various efficacies of H-U relaxation are considered in the nonstationary evolutions.
