Query: Testing gravity with cold atom interferometry: Results and prospects   Atom interferometers have been developed in the last three decades as new
powerful tools to investigate gravity. They were used for measuring the gravity
acceleration, the gravity gradient, and the gravity-field curvature, for the
determination of the gravitational constant, for the investigation of gravity
at microscopic distances, to test the equivalence principle of general
relativity and the theories of modified gravity, to probe the interplay between
gravitational and quantum physics and to test quantum gravity models, to search
for dark matter and dark energy, and they were proposed as new detectors for
the observation of gravitational waves. Here I describe past and ongoing
experiments with an outlook on what I think are the main prospects in this
field and the potential to search for new physics.
