Neutral-atom arrays trapped in optical potentials are a powerful platform for studying
quantum physics, combining precise single-particle control and detection with a range of …

Strontium optical lattice clocks have the potential to simultaneously interrogate millions of
atoms with a high spectroscopic quality factor of 4× 1017. Previously, atomic interactions …

We implement imaging spectroscopy of the optical clock transition of lattice-trapped
degenerate fermionic Sr in the Mott-insulating regime, combining micron spatial resolution …

The Einstein equivalence principle (EEP) has a central role in the understanding of gravity
and space–time. In its weak form, or weak equivalence principle (WEP), it directly implies …

We report the first realization of large momentum transfer (LMT) clock atom interferometry.
Using single-photon interactions on the strontium S 1 0-P 3 1 transition, we demonstrate …

The theory of general relativity describes macroscopic phenomena driven by the influence of
gravity while quantum mechanics brilliantly accounts for microscopic effects. Despite their …

We evaluate the sensitivity of a dual cloud atom interferometer to the measurement of
vertical gravity gradient. We study the influence of most relevant experimental parameters on …

Long-term inertial navigation is currently limited by the bias drifts of gyroscopes and
accelerometers and ultrastable cold-atom interferometers offer a promising alternative for …

We present a horizontal gravity gradiometer atom interferometer for precision gravitational
tests. The horizontal configuration is superior for maximizing the inertial signal in the atom …

Quantum sensors based on coherent matter-waves are precise measurement devices
whose ultimate accuracy is achieved with Bose–Einstein condensates (BECs) in extended …
