Since the first proof-of-principle experiments over 25 years ago, atom interferometry has
matured to a versatile tool that can be used in fundamental research in particle physics …

We review the field of atom interferometer inertial sensors. We begin by reviewing the path
integral formulation of atom interferometers and then specialize the treatment to light-pulse …

Owing to the low-gravity conditions in space, space-borne laboratories enable experiments
with extended free-fall times. Because Bose–Einstein condensates have an extremely low …

In contrast to light, matter-wave optics of quantum gases deals with interactions even in free
space and for ensembles comprising millions of atoms. We exploit these interactions in a …

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 …

Cold-atom inertial sensors target several applications in navigation, geoscience, and tests of
fundamental physics. Achieving high sampling rates and high inertial sensitivities, obtained …

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 …

Spacetime curvature induces tidal forces on the wave function of a single quantum system.
Using a dual light-pulse atom interferometer, we measure a phase shift associated with such …

We report the first realization of large momentum transfer (LMT) clock atom interferometry.
Using single-photon interactions on the strontium S 1 0-P 3 1 transition, we demonstrate …

Microgravity eases several constraints limiting experiments with ultracold and condensed
atoms on ground. It enables extended times of flight without suspension and eliminates the …
