We review the physics and phenomenology of wave dark matter: a bosonic dark matter
candidate lighter than about 30 eV. Such particles have a de Broglie wavelength exceeding …

We review the landscape of QCD axion models. Theoretical constructions that extend the
window for the axion mass and couplings beyond conventional regions are highlighted and …

“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 …

The last decade has seen unprecedented effort in dark matter model building at all mass
scales coupled with the design of numerous new detection strategies. Transformative …

The cosmological applications of atomic clocks,, so far have been limited to searches for the
uniform-in-time drift of fundamental constants. We point out that a transient-in-time change of …

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 …

Within the last decade, optical atomic clocks have surpassed the best cesium clocks, which
are used to realize the unit of time and frequency, in terms of accuracy and stability by about …

Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can
form stable, macroscopic field configurations in the form of topological defects that could …

The detection of variations of fundamental constants of the Standard Model would provide
us with compelling evidence of new physics, and could lift the veil on the nature of dark …
