abstract

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 $35-400\,\mu$eV, at least.

  1. Feebly-Interacting Peccei-Quinn Model

    hep-ph 2024-12 conditional novelty 7.0 of 10

    A feebly-interacting PQ scalar with large wave-function renormalization can generate a large axion decay constant while keeping all mass scales near the TeV scale, predicting a light PQ Higgs and new dark matter scenarios.

  2. Design of ALPHA Phase I: A Plasma Haloscope for 10--20 GHz Post-Inflation Axions

    hep-ex 2026-08 conditional novelty 6.0 of 10

    ALPHA Phase I is designed to probe axion dark matter at 40 to 80 micro-eV mass with projected KSVZ-level sensitivity using tunable wire-array plasma resonators.

  3. Axiverse Lampposts

    hep-ph 2026-02 conditional novelty 6.0 of 10

    In a hierarchical multi-axion theory with random couplings, axion field ranges shrink with 1/sqrt(N), generic axion–SM couplings are suppressed, but the QCD axion's coupling is unsuppressed.

  4. Atomic Quantum Sensors for High-Frequency Gravitational Wave Searches

    hep-ph 2025-10 conditional novelty 6.0 of 10

    A cavity-plus-atomic-sensor design could reach strain sensitivities down to ~1e-37 Hz^-1/2 in aggressive optical configurations, opening the unexplored high-frequency gravitational-wave band.

  5. Search for dark-matter axions beyond the quantum limit: the Cosmological Axion Sarov Haloscope (CASH) proposal

    hep-ph 2025-06 conditional novelty 6.0 of 10

    The CASH haloscope proposal projects that Josephson-junction single-photon detectors can reach axion-photon couplings below 1e-15 GeV^-1 in the 38-54 micro-eV mass range, beating the standard quantum limit.

  6. String Theory and Grand Unification Suggest a Sub-Microelectronvolt QCD Axion

    hep-ph 2025-05 conditional novelty 6.0 of 10

    String-theoretic axions consistent with grand unification and proton decay are predicted to have masses in the 3e-11 to 1e-8 eV window, with at most 47 axions in the Kreuzer-Skarke ensemble.

  7. Gravitational Wave Detection With Plasma Haloscopes

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A full analysis of gravitational wave detection in plasma haloscopes shows anisotropic wire arrays lose sensitivity at high frequency, while isotropic arrays recover it.

  8. Photon Propagation through Axion Clouds around Magnetized Compact Objects: Time Delays and Polarimetric Signatures

    hep-ph 2026-04 conditional novelty 5.0 of 10

    Magnetar-hosted axion clouds produce only ~10^-12 s photon delays and, if GRB polarization survives, imply a conditional benchmark g_aγγ ≲ 6×10^-14 GeV^-1 at m_a ~ 10^-4 eV.

    hep-ph 2025-01 conditional novelty 5.0 of 10

    A KSVZ-type axion framework generates Dirac neutrino masses through colored vector-like quarks and leptoquarks, linking neutrino mass, strong CP, and dark matter.

    gr-qc 2019-09 conditional novelty 4.0 of 10

    In Chern-Simons axion Einstein gravity, right- and left-handed gravitational wave polarizations obey different dispersion relations, and high-frequency damping is four times stronger than in general relativity.

    The Earth can act as a giant transducer: EM-coupled ultralight dark matter induces a global, radius-enhanced oscillating magnetic field, and existing magnetometer arrays already set leading direct constraints.
