“…The fluctuations would also lead to decoherence. The search for these effects requires high-sensitivity atom interferometry and a long evolution time so a prospect is to perform such experiments in microgravity [67,93,[205][206][207][208].…”

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.

“…Future space-based tests include STEP [77] and GG [78], which could reach sensitivities two or three orders of magnitude better than MICROSCOPE. Other promising opportunities for future studies include experiments utilizing drop towers [87], balloons [88], bouncing masses [89], and sounding rockets [90].…”

The effects of Lorentz and CPT violations on macroscopic objects are explored. Effective composite coefficients for Lorentz violation are derived in terms of coefficients for electrons, protons, and neutrons in the Standard-Model Extension, including all minimal and non-minimal violations. The hamiltonian and modified Newton’s second law for a test body are derived. The framework is applied to free-fall and torsion-balance tests of the weak equivalence principle and to orbital motion. The effects on continuous media are studied, and the frequency shifts in acoustic resonators are calculated.
