Abstract:
The interplay between low-energy quantum physics and general relativity offers phenomena that shed light on some fundamental principles of the two theories, and that may be probed in experiments. In recent years, “clock interferometry” has emerged as a new path to probe some aspects of this interplay. I will briefly discuss our results on interfering clocks in the presence of time dilation and the resulting decoherence [1,2]. I will then focus on the coupling of composite systems to the gravitational field, showing how the gravitational mass emerges for composite systems and resolving an old conundrum in general relativity [3].
