Unruh effects, Hawking Black Hole Evaporation, Quantum Corrected Larmor Formula, Numbers of Particles in Curved Spacetime: "Same-Same, but Just A Bit Different"

This paper explains the origin of the Unruh Temperature, in terms of disagreements, on the number of particles encountered between accelerated and inertial observers, and relates it to the conventional approach of Unruh accelerated detectors. It is not a new explanation. However, we argue that the same explanation applies to justify why (massive) accelerated charged particles radiate, leading to the Larmor formula, including its QED versions. We contend that not just the quantum corrections, but also the classical part, are just equivalent to the Unruh effects. It also explains why Hawking black hole radiation includes contributions both from particles escaping on the black hole horizon, and from particles created, by spacetime curvature changes, between the horizon and the asymptotic infinite away from the black hole. It is also why observers can’t agree on the number of particles present in a curved spacetime. The use of these phenomena to explain the full Larmor radiation formula, and the Hawking radiation derivation options may not be widely known. In fact, at the difference of recently published popular science articles about alleged first observation of Unruh radiations, the present paper argues that Unruh radiations have been observed from a long time: whenever an accelerated (massive) charged particle radiates, like for example in a radio source, antenna, or oscillator. In fact, the Larmor radiation can be extended to any Yang Mills interactions for accelerated massive particles, based on the Unruh effect. It has consequences on particle decays, with now the possibility for example that an “accelerated proton” decays due to the Unruh effect. We ruled out such decays in an inertial frame, but when accelerated, it is possible, and it still does not support GUTs. The paper also introduces the notion of Larmor gravitation radiation, that it exemplifies with frame dragging General Relativity (GR) effects, and the universe spacetime memory. It is then extended also to all the other interactions: QED, QCD, Electroweak. As a digression, we conclude that radiation when electron jump down to a lower level of energy in an atom are also Larmor radiations. Similarly, we present some considerations on the Schwinger effects and its relation to all this. We conclude with some multi-fold universe considerations, based on the microscopic composition of the spacetime of multi-fold universes (massless Higgs boson, including why gravity and entanglement break the Reeh-Schielder theorem.Cite as: Stephane H Maes, (2022), "Unruh effects, Hawking Black Hole Evaporation, Quantum Corrected Larmor Formula, Numbers of Particles in Curved Spacetime: "Same-Same, but Just A Bit Different"", https://doi.org/10.5281/zenodo.8306942, https://shmaesphysics.wordpress.com/2022/07/25/unruh-effects-hawking-black-hole-evaporation-quantum-corrected-larmor-formula-numbers-of-particles-in-curved-spacetime-same-same-but-just-a-bit-different/, July 25, 2022
