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 …

With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

Abstract The Einstein Telescope (ET), the European project for a third-generation
gravitational-wave detector, has a reference configuration based on a triangular shape …

We conduct frequency comparisons between a state-of-the-art strontium optical lattice clock,
a cryogenic crystalline silicon cavity, and a hydrogen maser to set new bounds on 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 …

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 …

Detection of a gravitational-wave signal of non-astrophysical origin would be a landmark
discovery, potentially providing a significant clue to some of our most basic, big-picture …

Strontium optical lattice clocks have the potential to simultaneously interrogate millions of
atoms with a high spectroscopic quality factor of 4× 1017. Previously, atomic interactions …

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 …

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 …
