“Quantum sensing” describes the use of a quantum system, quantum properties, or quantum
phenomena to perform a measurement of a physical quantity. Historical examples of …

Theories of modified gravity, where light scalars with non-trivial self-interactions and non-
minimal couplings to matter—chameleon and symmetron theories—dynamically suppress …

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

Traditional gravity measurements use bulk masses to both source and probe gravitational
fields. Matter-wave interferometers enable the use of probe masses as small as neutrons …

Explaining the origin of the acceleration of the expansion of the Universe remains as
challenging as ever. In this review, we present different approaches from dark energy to …

Atom interferometry experiments are searching for evidence of chameleon scalar fields with
ever-increasing precision. As experiments become more precise, so too must theoretical …

We present the results of a search for unknown interactions that couple to mass between an
optically levitated microsphere and a gold-coated silicon cantilever. The scale and geometry …

The chameleon model is a scalar field theory with a screening mechanism that explains how
a cosmologically relevant light scalar can avoid the constraints of intra-solar-system …

Among the known particles, the neutron is special because it provides experimental access
to all of the four fundamental forces and a wide range of hypothetical interactions. Despite …

Slow neutrons possess several advantageous properties which make them useful probes for
a variety of exotic interactions, including some that can form at least some components of the …
