Cancellation effects as a fingerprint of quantum collapse models at atomic scale

TL;DR

This paper investigates how dynamical wave-function collapse models induce spontaneous electromagnetic radiation in atomic systems at the X-ray scale, revealing species-dependent effects and differences from previous idealized models.

Contribution

It demonstrates for the first time that spontaneous radiation rates depend on atomic species and specific collapse models at low energies.

Findings

Radiation rate varies with atomic species.

Dependence on specific collapse models established.

Strong deviations from previous idealized cases.

Abstract

In this work the spontaneous electromagnetic radiation from atomic systems, induced by dynamical wave-function collapse, is investigated in the X-rays domain. Strong departures are evidenced with respect to the simple cases considered until now in the literature, in which the emission is either perfectly coherent (protons in the same nuclei) or incoherent (electrons). In this low-energy regime the spontaneous radiation rate strongly depends on the atomic species under investigation and, for the first time, is found to depend on the specific collapse model.
