DESCRIPTION:Light dark matter can scatter coherently from macroscopic test
  masses\, producing tiny accelerations that mimic violations of the weak
  equivalence principle. In this talk\, I will discuss how precision equi
 valence-principle experiments can be reinterpreted as detectors for light
  dark matter. I will first introduce the coherent enhancement mechanism f
 or sub-eV dark matter scattering from macroscopic targets and the resulti
 ng constraints from asymmetric torsion-balance experiments. I will then d
 escribe how intrinsic density fluctuations in heterogeneous materials ext
 end the coherent response to higher dark-matter masses\, allowing MICROSC
 OPE data to probe previously unexplored sub-keV parameter space. Together
 \, these results open a new avenue for searching for light dark matter wi
 th high-precision tests of gravity.\n\nhttps://indico.ijclab.in2p3.fr/eve
