Observation of a Gravitational Aharonov-Bohm Effect and its Implications for Quantum Superpositions of Newtonian Gravitational Fields

Lecture

Helmut Rauch Lecture

The gravitational interaction of a tungsten source mass with atomic wavepackets has been observed in an atom deBroglie wave interferometer, in a regime where the separation distance between the interfering wavepackets is comparable to their distance to the source mass. We will discuss this experiment in the context of Aharonov-Bohm effects. We will describe the relevance of these results to the observation of quantum superpositions of Newtonian gravitational fields.
