Sven Herrmann: Cold atom interferometry with extended free fall time - RQI Circuit Bremen 2023

Title: Cold atom interferometry with extended free fall time – recent progress and ideas

Abstract: Over the last decade, cold atom interferometry has matured into a sensitive tool that can be applied both for practical applications as well as sensitive tests of fundamental physics. In particular, several long baseline instruments as well as microgravity experiments with access to extended free fall times push the achievable sensitivity into new regimes. This holds the promise to explore the interface of gravity and quantum physics in new and exciting ways.

In my talk, I will first present some of our own work on interferometry with extended free fall times in the Bremen drop tower. I then want to discuss some of the recent ideas that have been brought forward to perform test experiments for gravity using interferometry on long baselines and with extended free fall.

Talk delivered at ZARM on November 24th 2023.
