We present a new exclusion bound of axion-like particle dark matter with axion-photon couplings above $\mathrm{10^{-13}}$ $\mathrm{GeV^{-1}}$ over the frequency range 4796.7--4799.5 MHz, corresponding to a narrow range of axion masses centered around 19.84 $\mu$eV. This measurement represents the first implementation of a Josephson Traveling Wave Parametric Amplifier (JTWPA) in a dark matter search. The JTWPA was operated in the insert of the Axion Dark Matter eXperiment (ADMX) as part of an independent receiver chain that was attached to a 0.588-liter cavity. The ability of the JTWPA to deliver high gain over a wide (3 GHz) bandwidth has engendered interest from those aiming to perform broadband axion searches, a longstanding goal in this field.

  1. A Near-Cutoff Waveguide Haloscope for sub-meV Dark Matter

    hep-ph 2026-05 unverdicted novelty 7.0

    A novel waveguide haloscope concept using near-cutoff slow-wave response for sub-meV bosonic dark matter, projecting dark photon sensitivity of ε≈2.1×10^{-15} at 0.1 meV.

  2. Resonant enhancement of axion dark matter decay

    hep-ph 2025-07 unverdicted novelty 6.0

    Resonant cavities enhance axion dark matter decay to two photons via the Purcell effect, offering a competitive search method implementable with pre-existing heterodyne detection schemes.

  3. Transient axion streams from disrupted miniclusters

    astro-ph.GA 2026-05 unverdicted novelty 5.0

    Axion streams from stellar disruptions of miniclusters dilute by factors up to 10^{-9}, making persistent dense streams rare near the Sun, while producing narrow linewidths of 10^{-7} to 10 Hz in haloscopes.
