Airborne absolute gravimetry with a quantum sensor, comparison with classical technologies
Yannick Bidel, Nassim Zahzam, Alexandre Bresson +14
We report an airborne gravity survey with an absolute gravimeter based on atom interferometry and two relative gravimeters: a classical LaCoste\&Romberg (L\&R) and a novel iMAR str…
MICROSCOPE mission: final results of the test of the Equivalence Principle
Pierre Touboul, Gilles Métris, Manuel Rodrigues +44
The MICROSCOPE mission was designed to test the Weak Equivalence Principle (WEP), stating the equality between the inertial and the gravitational masses, with a precision of $10^{-…
Solving nonlinear Klein-Gordon equations on unbounded domains via the Finite Element Method
Hugo Lévy, Joël Bergé, Jean-Philippe Uzan
A large class of scalar-tensor theories of gravity exhibit a screening mechanism that dynamically suppresses fifth forces in the Solar system and local laboratory experiments. Tech…
Hybrid electrostatic-atomic accelerometer for future space gravity missions
Nassim Zahzam, Bruno Christophe, Vincent Lebat +11
Long term observation of temporal Earth's gravity field with enhanced temporal and spatial resolution is a major objective for future satellite gravity missions. Improving the perf…
MICROSCOPE Mission scenario, ground segment and data processing
Manuel Rodrigues, Pierre Touboul, Gilles Métris +9
Testing the Weak Equivalence Principle (WEP) to a precision of requires a quantity of data that give enough confidence on the final result: ideally, the longer the measu…
Cold Atoms in Space: Community Workshop Summary and Proposed Road-Map
Ivan Alonso, Cristiano Alpigiani, Brett Altschul +246
We summarize the discussions at a virtual Community Workshop on Cold Atoms in Space concerning the status of cold atom technologies, the prospective scientific and societal opportu…
MICROSCOPE: systematic errors
Manuel Rodrigues, Pierre Touboul1, Gilles Metris +19
The MICROSCOPE mission aims to test the Weak Equivalence Principle (WEP) in orbit with an unprecedented precision of 10 on the Eötvös parameter thanks to electrostatic acce…
Atom interferometry using - Raman transitions between and
Jeanne Bernard, Yannick Bidel, Malo Cadoret +6
We report on the experimental demonstration of a horizontal accelerometer based on atom interferometry using counterpropagative Raman transitions between the states …
A cost-effective nonlinear extremum-preserving finite volume scheme for highly anisotropic diffusion on Cartesian grids, with application to radiation belt dynamics
Nour Dahmen, Jerome Droniou, Francois Rogier
We construct a new nonlinear finite volume (FV) scheme for highly anisotropic diffusion equations, that satisfies the discrete minimum-maximum principle. The construction relies on…
MICROSCOPE instrument in-flight characterization
Ratana Chhun, Emilie Hardy, Manuel Rodrigues +11
Since the MICROSCOPE instrument aims to measure accelerations as low as a few 10\,m\,s and cannot operate on ground, it was obvious to have a large time dedicated to…
MICROSCOPE's constraint on a short-range fifth force
Joel Bergé, Martin Pernot-Borràs, Jean-Philippe Uzan +5
The MICROSCOPE experiment was designed to test the weak equivalence principle in space, by comparing the low-frequency dynamics of cylindrical "free-falling" test masses controlled…
MICROSCOPE mission: Data analysis principle
Joel Bergé, Quentin Baghi, Emilie Hardy +10
After performing highly sensitive acceleration measurements during two years of drag-free flight around the Earth, MICROSCOPE provided the best constraint on the Weak Equivalence P…
MICROSCOPE mission analysis, requirements and expected performance
Pierre Touboul, Manuel Rodrigues, Gilles Métris +16
The MICROSCOPE mission aimed to test the Weak Equivalence Principle (WEP) to a precision of . The WEP states that two bodies fall at the same rate on a gravitational fiel…
Effect of trap symmetry and atom-atom interactions on a trapped atom interferometer with internal state labelling
M. Dupont-Nivet, C. I. Westbrook, S. Schwartz
In this paper, we study the dynamics of a trapped atom interferometer with internal state labelling in the presence of interactions. We consider two situations: an atomic clock in…
The local dark sector. Probing gravitation's low-acceleration frontier and dark matter in the Solar System neighborhood
Joel Bergé, Laura Baudis, Philippe Brax +18
We speculate on the development and availability of new innovative propulsion techniques in the 2040s, that will allow us to fly a spacecraft outside the Solar System (at 150 AU an…
Exploring the Foundations of the Universe with Space Tests of the Equivalence Principle
Baptiste Battelier, Joël Bergé, Andrea Bertoldi +34
We present the scientific motivation for future space tests of the equivalence principle, and in particular the universality of free fall, at the level or better. Two po…
A general study of chameleon fifth force in gravity space experiments
Martin Pernot-Borràs, Joel Bergé, Philippe Brax +1
This article investigates the profile of the scalar field of a scalar-tensor theory subject to the chameleon mechanism in the context of gravity space missions like the MICROSCOPE…
Zero-velocity atom interferometry using a retroreflected frequency chirped laser
Isadora Perrin, Jeanne Bernard, Yannick Bidel +4
Atom interferometry using stimulated Raman transitions in a retroreflected configuration is the first choice in high precision measurements because it provides low phase noise, hig…
