Particle physics today faces the challenge of explaining the mystery of dark matter, the origin
of matter over anti-matter in the Universe, the origin of the neutrino masses, the apparent …

Axions and other very light axion-like particles appear in many extensions of the Standard
Model, and are leading candidates to compose part or all of the missing matter of the …

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 …

Linear quantum measurements with independent particles are bounded by the standard
quantum limit, which limits the precision achievable in estimating unknown phase …

State-of-the-art atomic clocks are based on the precise detection of the energy difference
between two atomic levels, which is measured in terms of the quantum phase accumulated …

A new class of solutions to the electroweak hierarchy problem is presented that does not
require either weak-scale dynamics or anthropics. Dynamical evolution during the early …

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 …

We propose an experiment to search for QCD axion and axionlike-particle dark matter.
Nuclei that are interacting with the background axion dark matter acquire time-varying CP …

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 …
