Atomic Interferometry Test of Dark Energy

Understand

Atomic interferometry can be used to probe dark energy models coupled to matter.

• We consider the constraints coming from recent experimental results on models generalising the inverse power law chameleons such as $f(R)$ gravity in the large curvature regime, the environmentally dependent dilaton and symmetrons.
• Using the tomographic description of these models, we find that only symmetrons with masses smaller than the dark energy scale can be efficiently tested.
• In this regime, the resulting constraints complement the bounds from the E\"otwash experiment and exclude small values of the symmetron self-coupling.
