Helmut Rauch Lecture - Prof. Mark Kasevich (Stanford)

Vortrag

The Helmut Rauch Lecture is dedicated to the memory of Helmut Rauch, his pioneering achievements, and his lasting impact on quantum physics in Austria.

Mark Kasevich is the William R. Kenan, Jr. Professor of Physics and Applied Physics at Stanford University. His current research interests are centered on the development of quantum sensors based on cold atoms, the application of these sensors to tests of gravitation and quantum mechanics, the investigation of many-body quantum effects in cold atomic vapors, the investigation of entangled-state metrology methods, and the development of quantum-enhanced imaging methods.

 

Observation of a gravitational Aharonov-Bohm effect and its implications for quantum superpositions of Newtonian gravitational fields

 

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.
