Estimating subsurface water mass changes with ground-based gravimetry
Isabelle Schmidt, Jackson Ang'ong'a, Peter Bauer-Gottwein +10
Gravitational force is proportional to the mass of an attracting body; therefore, changes in subsurface mass can be detected using gravimetry. In the near subsurface, mass variatio…
Comparison of laser system designs for quantum technologies: BECCAL flight system vs. BECCAL ground test bed
Victoria A. Henderson, Jean-Pierre Marburger, André Wenzlawski +31
We present the design of laser systems for the Bose-Einstein Condensate and Cold Atom Laboratory (BECCAL) payload, enabling numerous quantum technological experiments onboard the I…
Additively manufactured ceramics for compact quantum technologies
Marc Christ, Conrad Zimmermann, Sascha Neinert +3
Quantum technologies are advancing from fundamental research in specialized laboratories to practical applications in the field, driving the demand for robust, scalable, and reprod…
Terrestrial Very-Long-Baseline Atom Interferometry: Workshop Summary
Sven Abend, Baptiste Allard, Iván Alonso +250
This document presents a summary of the 2023 Terrestrial Very-Long-Baseline Atom Interferometry Workshop hosted by CERN. The workshop brought together experts from around the world…
Light-Pulse Atom Interferometric Test of Continuous Spontaneous Localization
Sascha Vowe, Sandro Donadi, Vladimir Schkolnik +3
We investigate the effect of the Continuous Spontaneous Localization (CSL) model on light-pulse atom interferometry. Using a path-integral approach with an additional stochastic po…
Linien: A versatile, user-friendly, open-source FPGA-based tool for frequency stabilization and spectroscopy parameter optimization
Benjamin Wiegand, Bastian Leykauf, Robert Jördens +1
We present a user-friendly and versatile tool for laser frequency stabilization. Its main focus is spectroscopy locking, but the software is suitable for lock-in techniques in gene…
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…
ELGAR -- a European Laboratory for Gravitation and Atom-interferometric Research
B. Canuel, S. Abend, P. Amaro-Seoane +55
Gravitational Waves (GWs) were observed for the first time in 2015, one century after Einstein predicted their existence. There is now growing interest to extend the detection band…
A single-laser alternating-frequency magneto-optical trap
B. Wiegand, B. Leykauf, K. Döringshoff +3
In this paper, we present a technique for magneto-optical cooling and trapping of neutral atoms using a single laser. The alternating-frequency magneto-optical trap (AF-MOT) uses a…
Observation of vector and tensor light shifts in 87Rb using near-resonant, stimulated Raman spectroscopy
Qing-Qing Hu, Christian Freier, Yuan Sun +5
We present the derivation of the frequency dependent scalar, vector, and tensor dynamical polarizabilities for the two hyperfine levels of the 87Rb atom 5s ground state. Based on t…
Mapping the absolute magnetic field and evaluating the quadratic Zeeman effect induced systematic error in an atom interferometer gravimeter
Qing-Qing Hu, Christian Freier, Bastian Leykauf +4
Precisely evaluating the systematic error induced by the quadratic Zeeman effect is important for developing atom interferometer gravimeters aiming at an accuracy in the regime ( )…
