Sagnac interferometry and non-Newtonian gravity

TL;DR

This paper investigates how Sagnac interferometry can be used to detect non-Newtonian gravitational effects, specifically exploring a previously untested range of force ranges exceeding 10^14 meters.

Contribution

It demonstrates that Sagnac interferometry can probe non-Newtonian gravity at very large distance scales beyond current experimental limits.

Findings

Potential to explore force ranges $\lambda \geq 10^{14}$ m

Extends the application of Sagnac interferometry to non-Newtonian gravity

Identifies new experimental possibilities for gravity research

Abstract

Sagnac interferometry has been employed in the context of gravity as a proposal for the detection of the so called gravitomagnetic effect. In the present work we explore the possibilities that this experimental device could open up in the realm of non--Newtonian gravity. It will be shown that this experimental approach allows us to explore an interval of values of the range of the new force that up to now remains unexplored, namely, $\lambda\geq 10^{14}$ m.
