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 …

We propose a new strategy for searching for dark matter axions using tunable cryogenic
plasmas. Unlike current experiments, which repair the mismatch between axion and photon …

The next generation of axion direct-detection experiments may rule out or confirm axions as
the dominant source of dark matter. We develop a general likelihood-based framework for …

A well-motivated class of dark matter candidates, including axions and dark photons, takes
the form of coherent oscillations of a light bosonic field. If the dark matter couples to standard …

Antiferromagnetically doped topological insulators (ATI) are among the candidates to host
dynamical axion fields and axion polaritons, weakly interacting quasiparticles that are …

The axion emerges in extensions of the Standard Model that explain the absence of CP
violation in the strong interactions. Simultaneously, it can provide naturally the cold dark …

A bstract We show that the couplings of axions to gauge bosons are highly restricted in
Grand Unified Theories where the standard model is embedded in a simple 4D gauge …

Axion dark matter can resonantly convert to photons in the magnetosphere of neutron stars,
possibly giving rise to radio signals observable on Earth. This method for the indirect …

The next generation of ultralight dark matter (DM) direct detection experiments, which could
confirm sub-eV bosons as the dominant source of DM, will feature multiple detectors …

In this report we present the status of the MAgnetized Disk and Mirror Axion eXperiment
(MADMAX), the first dielectric haloscope for the direct search of dark matter axions in the …
