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 …

The dark photon is a massive hypothetical particle that interacts with the Standard Model by
kinetically mixing with the visible photon. For small values of the mixing parameter, dark …

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 …

It has been suggested that certain antiferromagnetic topological insulators contain axion
quasiparticles (AQs), and that such materials could be used to detect axion dark matter …

We summarize the recent progress of the Axion Longitudinal Plasma Haloscope (ALPHA)
Consortium, a new experimental collaboration to build a plasma haloscope to search for …

Besides CP-preserving interactions, axions and axion-like particles may also have small CP-
violating scalar Yukawa interactions with nucleons and electrons. Any such interaction will …

With the increasing interest in dark matter axion detection through haloscopes, in which
different international groups are currently involved, the RADES group was established in …

We propose, design and construct a variant of the conventional axion haloscope concept
that could be competitive in the search for dark matter axions of masses in the decade 10 …

We develop a formalism to describe extensions of existing axion haloscope designs to those
that possess directional sensitivity to incoming dark matter axion velocities. The effects are …

Dark photons (DPs) produced in the early Universe are well-motivated dark matter (DM)
candidates. We show that the recently proposed tunable plasma haloscopes are particularly …
