Using optomechanical systems to test gravitational theory -- possibilities and limitations — •Dennis Rätzel — ZARM, University of Bremen, 28359 Bremen, Germany — Institut für Physik, Humboldt-Universität zu Berlin, 12489 Berlin, Germany

More than 100 years after the first development of a relativistic theory of gravity, there is an ever-increasing amount of predicted, yet untested, phenomena and unsolved scientific puzzles revolving around gravity. There are many proposals to apply quantum sensors to test for such phenomena or experimentally resolve some of the puzzles. In this talk, I will present my perspective on three proposals based on optomechanical systems: measurement of the gravitational field of light and relativistic particle beams, obtaining bounds on Chameleon-field dark energy models, and testing for quantum properties of the gravitational field. I will give a short introduction to the models involved and discuss fundamental constraints.
