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…
Dual Open Atom Interferometry for Compact and Mobile Quantum Sensing
Yosri Ben-Aïcha, Zain Mehdi, Christian Freier +12
We demonstrate an atom interferometer measurement protocol compatible with operation on a dynamic platform. Our method employs two open interferometers, derived from the same atomi…
Enhancing Inertial Navigation Performance via Fusion of Classical and Quantum Accelerometers
Xuezhi Wang, Allison Kealy, Christopher Gilliam +11
While quantum accelerometers sense with extremely low drift and low bias, their practical sensing capabilities face two limitations compared with classical accelerometers: a lower…
Readout delay free Bragg atom interferometry using overlapped spatial fringes
P. B. Wigley, K. S. Hardman, C. Freier +5
A method for mitigating the readout delay characteristic of Bragg-based atom interferometry is presented, utilizing an asymmetric Mach-Zehnder interferometer sequence to generate s…
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 ( )…
Mobile quantum gravity sensor with unprecedented stability
Christian Freier, Matthias Hauth, Vladimir Schkolnik +6
Changes of surface gravity on Earth are of great interest in geodesy, earth sciences and natural resource exploration. They are indicative of Earth system's mass redistributions an…
The effect of wavefront aberrations in atom interferometry
Vladimir Schkolnik, Bastian Leykauf, Matthias Hauth +2
Wavefront aberrations are one of the largest uncertainty factors in present atom interferometers. We present a detailed numerical and experimental analysis of this effect based on…
