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 …

We discuss the basic physics and instrumentation issues related to high-performance
physical and inertial sensors based on atomic spectroscopy. Recent work on atomic …

About 300 experiments have tried to determine the value of the Newtonian gravitational
constant, G, so far, but large discrepancies in the results have made it impossible to know its …

The ability to measure tiny variations in the local gravitational acceleration allows, besides
other applications, the detection of hidden hydrocarbon reserves, magma build-up before …

Atom interferometers have been developed in the last three decades as new powerful tools
to investigate gravity. They were used for measuring the gravity acceleration, the gravity …

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 …

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 …

General Relativity is today the best theory of gravity addressing a wide range of phenomena.
Our understanding of physical laws, from cosmology to local scales, cannot be properly …

We evaluate the sensitivity of a dual cloud atom interferometer to the measurement of
vertical gravity gradient. We study the influence of most relevant experimental parameters on …

We report on a high precision measurement of gravitational acceleration using ultracold
strontium atoms trapped in a vertical optical lattice. Using amplitude modulation of the lattice …
