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 …

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 …

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 …

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 …

All existing quantum-gravity proposals are extremely hard to test in practice. Quantum effects
in the gravitational field are exceptionally small, unlike those in the electromagnetic field …

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 …

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 …

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 …
