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 …

We use a dual-species atom interferometer with 2 s of free-fall time to measure the relative
acceleration between Rb 85 and Rb 87 wave packets in the Earth's gravitational field …

We outline the experimental concept and key scientific capabilities of AION (Atom
Interferometer Observatory and Network), a proposed experimental programme using cold …

We propose in this White Paper a concept for a space experiment using cold atoms to
search for ultra-light dark matter, and to detect gravitational waves in the frequency range …

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 …

Numerous astrophysical and cosmological observations are best explained by the existence
of dark matter, a mass density which interacts only very weakly with visible, baryonic matter …

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 …

We present a new framework to study the time variation of fundamental constants in a model-
independent way. Model independence implies more free parameters than assumed in …

A bstract We discuss models of ultralight scalar Dark Matter (DM) with linear and quadratic
couplings to the Standard Model (SM). In addition to studying the phenomenology of linear …
