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 …

Advances in quantum technologies are giving rise to a revolution in the way fundamental
physics questions are explored at the empirical level. At the same time, they are the seeds …

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 …

The traditional view from particle physics is that quantum gravity effects should only become
detectable at extremely high energies and small length scales. Due to the significant …

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 …

An ensemble of atoms can operate as a quantum sensor by placing atoms in a
superposition of two different states. Upon measurement of the sensor, each atom is …

The last decade has seen unprecedented effort in dark matter model building at all mass
scales coupled with the design of numerous new detection strategies. Transformative …

Despite being the dominant force of nature on large scales, gravity remains relatively elusive
to precision laboratory experiments. Atom interferometers are powerful tools for …

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