Principal Component Analysis for Spatial Phase Reconstruction in Atom Interferometry
Stefan Seckmeyer, Holger Ahlers, Jan-Niclas Kirsten-Siemß +4
Atom interferometers are sensitive to a wide range of forces by encoding their signals in interference patterns of matter waves. To estimate the magnitude of these forces, the unde…
Multi-loop atomic Sagnac interferometry
Christian Schubert, Sven Abend, Matthias Gersemann +4
The sensitivity of light and matter-wave interferometers to rotations is based on the Sagnac effect and increases with the area enclosed by the interferometer. In the case of light…
Precision inertial sensing with quantum gases
Thomas Hensel, Sina Loriani, Christian Schubert +7
Quantum sensors based on light-pulse atom interferometers allow for high-precision measurements of inertial and electromagnetic forces such as the accurate determination of fundame…
Technologies for the ELGAR large scale atom interferometer array
B. Canuel, S. Abend, P. Amaro-Seoane +56
We proposed the European Laboratory for Gravitation and Atom-interferometric Research (ELGAR), an array of atom gradiometers aimed at studying space-time and gravitation with the p…
Analytic theory for Bragg atom interferometry based on the adiabatic theorem
Jan-Niclas Siemß, Florian Fitzek, Sven Abend +3
High-fidelity Bragg pulses are an indispensable tool for state-of-the-art atom interferometry experiments. In this paper, we introduce an analytic theory for such pulses. Our theor…
Atom interferometry and its applications
Sven Abend, Matthias Gersemann, Christian Schubert +7
We provide an introduction into the field of atom optics and review our work on interferometry with cold atoms, and in particular with Bose-Einstein condensates. Here we emphasize…
