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 …

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 …

In this paper, we study the local observational consequences of a violation of the Einstein
equivalence principle induced by models of light scalar dark matter (DM). We focus on two …

Recent advances in optical atomic clocks and optical time transfer have enabled new
possibilities in precision metrology for both tests of fundamental physics and timing …

Dark matter may induce apparent temporal variations in the physical “constants”, including
the electromagnetic fine-structure constant and fermion masses. In particular, a coherently …

The field of particle physics is in a peculiar state. The standard model of particle theory
successfully describes every fundamental particle and force observed in laboratories, yet …

Recent advances in quantum sensors, including atomic clocks, enable searches for a broad
range of dark matter candidates. The question of the dark matter distribution in the Solar …

Pulsar timing arrays (PTAs) are exceptionally sensitive detectors in the frequency band
nHz≲ f≲ μ Hz. Ultralight dark matter (ULDM), with mass in the range 10-23 eV≲ m ϕ≲ 10-20 …

The exchange of spin-0 or spin-1 bosons between fermions or spin-polarized macroscopic
objects gives rise to various spin-dependent potentials. We derive the coordinate-space …

The nature of dark matter remains unknown to date, although several candidate particles are
being considered in a dynamically changing research landscape. Scalar field dark matter is …
