HYBRID: Matter Wave Interferometry for Inertial Sensing and Tests of Fundamental Physics

This lecture will be held in presence of a limited audience at Magnus-Haus and can be followed online at the same time. Use the links above to register your attendance in person on site or to receive access information for online attendance.

The 2G-plus rule applies to this event. The additional testing requirement does not apply to those who have been fully vaccinated (two vaccinations plus one booster shot), those who have been vaccinated twice within the last three months without a booster shot vaccination (including recently vaccinated convalescents) or those who have been convalesced within the last three months (including recently convalesced vaccinees). An electronically verifiable proof of vaccination or a Covid-19 certificate of recovery and an identity document must be presented at the entrance. All visitors are required to wear mouth/nose coverings (except during the lecture) and to disinfect their hands at the entrance. The number of on-site participants is limited for infection control reasons. Please cancel by phone or email if you are unable to attend so that those waiting can move up. No admission after the start of the event. Please do not participate if you have symptoms of a possible SARS Covid 19 infection (cold symptoms).

Topic: State-of-the-art atom inertial sensors require improved control over noise and systematics to fully exploit the potential of large scale factors on ground and in space. We report on developments of the Very Long Baseline Atom Interferometry (VLBAI) facility. Stretching over 17 m, it features high-performance magnetic shielding and seismic attenuation as well as Rb & Yb sources. It will allow us to take on competition with superconducting gravimeters and to test the Universality of Free Fall at levels of parts in 10^13 and below. We will moreover report on matter-wave sensors in dynamic environments enhanced with opto-mechanical sensors and on fully geometries to discuss the prospects in inertial navigation and fundamental physics.

CV: Dennis Schlippert studied physics in Hannover (including a research stay at JPL/Caltech) and received his PhD from Leibniz Universität Hannover (including a research stay at UC Berkeley) in 2014 for performing the first quantum test of the universality of free fall using two different chemical species. After a period as a PostDoc he started leading a group focusing on guided atom interferometry for inertial navigation and fundamental physics funded through the BMBF Quantum Futur Award in 2018. He has (co-)supervised 8 ESRs (2 completed, 6 ongoing) and also leads the team pursuing a matter wave test of Einstein's Equivalence Principle (Rb-K) and takes scientific lead of the VLBAI (Very Long Baseline Atom Interferometer) research facility.

Following the lecture, there will be a get-together where participants can exchange ideas with each other over pizza and drinks in the Remise and the garden of the Magnus-Haus.

The event is sponsored by the Wilhelm and Else Heraeus Foundation.
