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 …

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 …

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 …

Atomtronics is an emerging field that aims to manipulate ultracold atom moving in matter-
wave circuits for fundamental studies in both quantum science and technological …

Deployment of ultracold atom interferometers (AI) into space will capitalize on quantum
advantages and the extended freefall of persistent microgravity to provide high-precision …

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 …

Abstract Bose-Einstein condensates (BECs) in free fall constitute a promising source for
space-borne interferometry. Indeed, BECs enjoy a slowly expanding wave function, display …

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 …
