“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 …

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 …

After a decade and a half of research motivated by the accelerating universe, theory and
experiment have reached a certain level of maturity. The development of theoretical models …

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

Atom interferometers have been developed in the last three decades as new powerful tools
to investigate gravity. They were used for measuring the gravity acceleration, the gravity …

If dark energy, which drives the accelerated expansion of the universe, consists of a light
scalar field, it might be detectable as a “fifth force” between normal-matter objects, in …

Presently under construction in Lund, Sweden, the European Spallation Source (ESS) will
be the world's brightest neutron source. As such, it has the potential for a particle physics …

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 …

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

Various theories have been proposed for the nature of dark energy. It is therefore essential
to directly verify or rule out these theories by experiment. Despite substantial efforts in …
