Constraining symmetron fields with atom interferometry

TL;DR

This paper uses atom interferometry experiments to set new constraints on symmetron fields, excluding previously untested parameter regions and exploring domain wall formation as a way to differentiate screening models.

Contribution

It introduces novel constraints on the symmetron model using atom interferometry and discusses domain wall networks as a method to distinguish screening mechanisms.

Findings

New experimental constraints exclude previously untested symmetron parameter space.

Potential formation of domain wall networks in vacuum chambers.

Discussion of using domain walls to differentiate screening models.

Abstract

We apply the new constraints from atom-interferometry searches for screening mechanisms to the symmetron model, finding that these experiments exclude a previously unexplored region of parameter space. We discuss the possibility of networks of domain walls forming in the vacuum chamber, and how this could be used to discriminate between models of screening.
