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 …

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 …

We use a dual-species atom interferometer with 2 s of free-fall time to measure the relative
acceleration between Rb 85 and Rb 87 wave packets in the Earth's gravitational field …

Quantum mechanics governs the microscopic world, where low mass and momentum reveal
a natural wave–particle duality. Magnifying quantum behaviour to macroscopic scales is a …

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 …

We propose in this White Paper a concept for a space experiment using cold atoms to
search for ultra-light dark matter, and to detect gravitational waves in the frequency range …

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 …

Atom interferometers are powerful tools for both measurements in fundamental physics and
inertial sensing applications. Their performance, however, has been limited by the available …

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 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 …
