We simultaneously measure the gravitationally induced phase shift in two Raman-type
matter-wave interferometers operated with laser-cooled ensembles of Rb 87 and K 39 …

We present the MIGA experiment, an underground long baseline atom interferometer to
study gravity at large scale. The hybrid atom-laser antenna will use several atom …

The theory of general relativity describes macroscopic phenomena driven by the influence of
gravity while quantum mechanics brilliantly accounts for microscopic effects. Despite their …

We summarise the discussions at a virtual Community Workshop on Cold Atoms in Space
concerning the status of cold atom technologies, the prospective scientific and societal …

We study a space-based gravity gradiometer based on cold atom interferometry and its
potential for the Earth's gravitational field mapping. The instrument architecture has been …

Abstract We describe the Quantum Test of the Equivalence principle and Space Time
(QTEST), a concept for an atom interferometry mission on the International Space Station …

Wavefront aberrations are one of the largest uncertainty factors in present atom
interferometers. We present a detailed numerical and experimental analysis of this effect …

Low noise underground environments offer conditions allowing assessment of ultimate
performance of high sensitivity sensors such as accelerometers, gyrometers …

We present the scientific motivation for future space tests of the equivalence principle, and in
particular the universality of free fall, at the 10− 17 level or better. Two possible mission …

Matter-wave interferometers utilizing different isotopes or chemical elements intrinsically
have different sensitivities, and the analysis tools available until now are insufficient for …
