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 …

Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

MAGIS-100 is a next-generation quantum sensor under construction at Fermilab that aims to
explore fundamental physics with atom interferometry over a 100 m baseline. This novel …

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 …

The research on cold-atom interferometers gathers a large community of about 50 groups
worldwide both in the academic and now in the industrial sectors. The interest in this sub …

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 …

Abstract The Feynman-Tan relation, obtained by combining the Feynman energy relation
with the Tan's two-body contact, can explain the excitation spectra of strongly interacting 39K …

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 …

In an ideal test of the equivalence principle, the test masses fall in a common inertial frame.
A real experiment is affected by gravity gradients, which introduce systematic errors by …
