We report the 2018 self-consistent values of constants and conversion factors of physics and
chemistry recommended by the Committee on Data of the International Science Council …

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 …

The sensing of gravity has emerged as a tool in geophysics applications such as
engineering and climate research,–, including the monitoring of temporal variations in …

Gravity curves space and time. This can lead to proper time differences between freely
falling, nonlocal trajectories. A spatial superposition of a massive particle is predicted to be …

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 …

Gravity is the weakest of all known fundamental forces and poses some of the most
important open questions to modern physics: it remains resistant to unification within the …

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 …

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 …

Measuring gravity from an aircraft or a ship is essential in geodesy, geophysics, mineral and
hydrocarbon exploration, and navigation. Today, only relative sensors are available for …

The quantum superposition principle allows massive particles to be delocalized over distant
positions. Though quantum mechanics has proved adept at describing the microscopic …
