Non--Newtonian gravity and coherence properties of light

TL;DR

This paper explores how non-Newtonian gravity, such as a hypothetical fifth force, could influence the coherence properties of light, potentially enabling detection of new gravitational interactions through optical correlation measurements.

Contribution

It demonstrates that the effects of a fifth force on light's coherence functions could be used to detect non-Newtonian gravitational contributions, providing a novel experimental approach.

Findings

Theoretical analysis of fifth force effects on light coherence

Constraints on experimental parameters for detection

Potential for optical methods to reveal new gravitational forces

Abstract

In this work the possibility of detecting a non--Newtonian contribution to the gravitational potential by means of its effects upon the first and second--order coherence properties of light is analyzed. It will be proved that, in principle, the effects of a fifth force upon the correlation functions of electromagnetic radiation could be used to detect the existence of new forces. Some constraints upon the experimental parameters will also be deduced.
