questions in the fundamental physics domain. They include the validity of Einstein's …

As a powerful tool in scientific research and industrial technologies, the cold atom absolute
gravity sensor (CAGS) based on cold atom interferometry has been proven to be the most …

The capability to reach ultracold atomic temperatures in compact instruments has recently
been extended into space,. Ultracold temperatures amplify quantum effects, whereas free …

High frequency gravitational waves can be detected by observing the frequency modulation
they impart on photons. We discuss fundamental limitations to this method related to the fact …

Ultracold quantum gases are ideal sources for high-precision space-borne sensing as
proposed for Earth observation, relativistic geodesy and tests of fundamental physical laws …

Atomic, molecular, and optical (AMO) physics has been at the forefront of the development of
quantum science while laying the foundation for modern technology. With the growing …

A major challenge for gravitational-wave (GW) detection in the μ Hz band is engineering a
test mass (TM) with sufficiently low acceleration noise. We propose a GW detection concept …

A bstract We discuss models of ultralight scalar Dark Matter (DM) with linear and quadratic
couplings to the Standard Model (SM). In addition to studying the phenomenology of linear …

Atom interferometers offer promising new avenues for detecting ultralight dark matter
(ULDM). The exceptional sensitivity of atom interferometers to fluctuations in the local …

Dark compact objects (“clumps”) transiting the Solar System exert accelerations on the test
masses (TM) in a gravitational-wave (GW) detector. We reexamine the detectability of these …
