“…The black lines bracket the traditional axion model band, 0.746 < |Caγ| < 1.92. Existing limits are displayed in gray, with coloured regions corresponding to proposed experiments (red tones for cavities, blue for dielectric haloscopes) [13,14,20,44,[46][47][48][49][50][51][52].…”

Tunable Axion Plasma Haloscopes

We propose a new strategy to search for dark matter axions using tunable cryogenic plasmas. Unlike current experiments, which repair the mismatch between axion and photon masses by breaking translational invariance (cavity and dielectric haloscopes), a plasma haloscope enables resonant conversion by matching the axion mass to a plasma frequency. A key advantage is that the plasma frequency is unrelated to the physical size of the device, allowing large conversion volumes. We identify wire metamaterials as a promising candidate plasma, wherein the plasma frequency can be tuned by varying the interwire spacing. For realistic experimental sizes we estimate competitive sensitivity for axion masses 35 − 400 µeV, at least.

“…Searches based on cavity resonators in strong magnetic fields [11] like ADMX [12], HAYSTAC [13], CUL-TASK [14], KLASH [15] or ORGAN [16] are optimal for m a 10 µeV. Significantly lower values of m a can be explored by LC circuits [17,18] or nuclear magnetic resonance techniques like CASPER [19].…”

“…The continuing dashed lines show plausible uncertainties. We also show, in grey, the current bounds on axion DM (ADMX [106,107],BRF) and, in green, prospects for next generation axion dark matter experiments, such as ADMX [106,107], CAPP [108], HAYSTAC [109], MADMAX [111,112], ORPHEUS [113,114], and the helioscope IAXO [115] (fiducial, extended+ sensitivities to the axion-photon channel and IAXOeγ for the electron-photon channel).

The Standard Model (SM) of particle physics is a big success. However, it lacks explanations for cosmic inflation, the matter-anti-matter asymmetry of the Universe, dark matter, neutrino oscillations, and the feebleness of CP violation in the strong interactions. The latter may be explained by a complex scalar field charged under a spontaneously broken global U(1) Peccei-Quinn (PQ) symmetry. Moreover, the pseudo Nambu-Goldstone boson of this breaking -the axion-may play the role of the dark matter. Furthermore, the modulus of the PQ field is a candidate for driving inflation. If additionally three extra SM singlet neutrinos (whose mass is induced by the PQ field) are included, the five aforementioned problems can be addressed at once. We review the SM extension dubbed SMASH -for SM-Axion-Seesaw-Higgs portal inflation-, discuss its predictions and tests in astrophysics, cosmology, and laboratory experiments. Variants of SMASH are also considered and commented on.
