Atomic Interferometry Test of Dark Energy
  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.
