This article reviews recent developments in tests of fundamental physics using atoms and
molecules, including the subjects of parity violation, searches for permanent electric dipole …

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 …

Measurements of the fine-structure constant α require methods from across subfields and
are thus powerful tests of the consistency of theory and experiment in physics. Using the …

A key step toward demonstrating a quantum system that can address difficult problems in
physics and chemistry will be performing a computation beyond the capabilities of any …

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 report the operation of a cold-atom inertial sensor which continuously captures the
rotation signal. Using a joint interrogation scheme, where we simultaneously prepare a cold …

The Einstein equivalence principle (EEP) has a central role in the understanding of gravity
and space–time. In its weak form, or weak equivalence principle (WEP), it directly implies …

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 …

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 on the realization of a matter-wave interferometer based on single-photon
interaction on the ultranarrow optical clock transition of strontium atoms. We experimentally …
