In this session we cover all laboratory experiments testing gravity and the structure of space-time using classical matter, light, and quantum matter. The latter includes atomic clocks, matter wave interferometry, entangled states, etc. We are first dealing with experiments exploring the structure of space-time as it is encoded in the Einstein Equivalence Principle (EEP). This includes tests of the Universality of Free Fall, the Universality of the Gravitational Redshift, and Local Lorentz Invariance, in the classical as well as in the quantum domain. These tests determine the space-time geometry. The next group of tests will explore the field equation of gravity which in most cases is encoded in the PPN formalism; more general formalisms like Finsler geometry, Doubly Special Relativity, etc. also need to be included. The third group of tests deals with testing the predictions of GR. This also will include applications like geodesy, positioning and metrology.

Talk in the parallel session

With the recent direct observation of gravitational waves, a new avenue of observing the Universe has become available. As a result, much effort is being devoted to the design of new detectors sensitive to different gravitational wave sources. One unique proposal is to detect gravitational waves using a Bose-Einstein Condensate (BEC) by using quantum metrology.
In this talk, I will show that...
