Mark Kasevich on Observation of a gravitational Aharonov-Bohm effect and its implications for quantum superpositions of Newtonian gravitational fields.
TU The Sky (TU Wien) Getreidemarkt 9, 1060 Vienna on 4 May 2023 at 4 PM
In memory of quantum optics pioneer Helmut Rauch, Mark Kasevich of Stanford University will deliver the first Helmut Rauch Lecture. In his talk, he will discuss the implications of a gravitational Aharonov-Bohm effect on quantum superpositions of Newtonian gravitational fields.
Helmut Rauch Lecture is dedicated to the memory of Helmut Rauch, his pioneering achievements, and his lasting impact on quantum physics in Austria. The event is a joint initiative between TU Wien and the Austrian Academy of Sciences and is supported by The Vienna Center for Quantum Science and Technology (VCQ).
“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.
