“…Observations of galaxies with SKA can potentially reach sensitivity comparable to ALPS-II for m a ∈ ½4 × 10 −7 ; 3 × 10 −4 eV by searching for stimulated decay of relic ALPs in galactic magnetic fields [108,109]. Dark matter ALPs can also convert to radio photons in the magnetospheres of neutron stars, leading to constraints in the μeV mass-range [110,111]. We show the limits from Ref.…”

Dark matter targets for axionlike particle searches

Many existing and proposed experiments targeting QCD axion dark matter (DM) can also search for a broad class of axionlike particles (ALPs). We analyze the experimental sensitivities to electromagnetically coupled ALP DM in different cosmological scenarios with the relic abundance set by the misalignment mechanism. We obtain benchmark DM targets for the standard thermal cosmology, a pre-nucleosynthesis period of early matter domination, and a period of kination. These targets are theoretically simple and assume Oð1Þ misalignment angles, avoiding fine-tuning of the initial conditions. We find that some experiments will have sensitivity to these ALP DM targets before they are sensitive to the QCD axion, and others can potentially reach interesting targets below the QCD band. The ALP DM abundance also depends on the origin of the ALP mass. Temperature-dependent masses that are generated by strong dynamics (as for the QCD axion) correspond to DM candidates with smaller decay constants, resulting in even better detection prospects.

“…Due to the new coupling and the possible oscillations among the three light bosons, the radio flux from the neutron star may be different from the benchmark value in Ref. [36], since it is determined by many sources, such as the property of the mass matrix, the properties of the external (dark) magnetic field, the axion dark matter density and so on.…”

We present the extended electrodynamics in the presence of the axion and dark photon. We derive the extended versions of Maxwell's equations and dark Maxwell's equations (for both massive and massless dark photons) as well as the wave equations. We discuss the implications of this extended electrodynamics including the enhanced effects in the particle conversions under the external magnetic or dark magnetic field. We also discuss the recently reported anomaly in the redshifted 21cm spectrum using the extended electrodynamics.

“…As such, a signal in the range 98 GHz ≤ ω/2π ≤ 137 GHz might be expected for the conditions of the experiment proposed in Refs. [34,53], based on axion dark matter conversion (notice that in our case we do not need a dark matter background). At this stage, however, we can not commit whether or not the axions produced via streaming instability can be detected within the sensitivity of telescopes such as CAST or the Arecibo Telescope for the typical observation periods (this would involve a more detailed calculation of the beam injection rates, intensity, energies etc.…”

Axion production in unstable magnetized plasmas

Axions, the hypothetical particles restoring the charge-parity symmetry in the strong sector of the Standard Model, and one of the most prone candidates for dark matter, are well-known to interact with plasmas. In a recent publication [Phys. Rev. Lett. 120, 181803 (2018)], we have shown that if the plasma dynamically responds to the presence of axions, then a new quasi-particle (the axion plasmon-polariton) can be formed, being at the basis of a new generation of plasma-based detection techniques. In this work, we exploit the axion-plasmon hybridization to actively produce axions in streaming magnetized plasmas. The produced axions can then be detected by reconversion into photons, in a scheme that is similar to the light-shining-a-wall experiments.
