abstract

We point out that photon regeneration-experiments that search for the axion, or axion-like particles, may be resonantly enhanced by employing matched Fabry-Perot optical cavities encompassing both the axion production and conversion magnetic field regions. Compared to a simple photon regeneration experiment, which uses the laser in a single-pass geometry, this technique can result in a gain in rate of order ${\cal F}^2$, where ${\cal F}$ is the finesse of the cavities. This gain could feasibly be $10^{(10-12)}$, corresponding to an improvement in sensitivity in the axion-photon coupling, $g_{a\gamma\gamma}$ , of order ${\cal F}^{1/2} \sim 10^{(2.5-3)}$, permitting a practical purely laboratory search to probe axion-photon couplings not previously excluded by stellar evolution limits, or solar axion searches.

  1. Any Light Particle Searches with ALPS II: first science results

    hep-ex 2025-12 unverdicted novelty 7.0 of 10

    ALPS II reports no detection of axion-like particles and establishes improved 95% CL upper limits on di-photon couplings of 1.5e-9 GeV^-1 for masses below 0.1 meV, plus limits for scalar, vector, and tensor bosons.

  2. Quantum and Material Effects in Undulator-Based LSW Searches for Dark Photons

    hep-ph 2025-07 conditional novelty 6.0 of 10

    Undulator-based light-shining-through-a-wall searches for dark photons, including wave-packet, wall, and air effects, could beat current laboratory limits by orders of magnitude.

  3. Deep Reinforcement Learning Based Routing for Heterogeneous Multi-Hop Wireless Networks

    eess.SP 2025-08 unverdicted novelty 5.0 of 10

    A DQN routing scheme with channel-based neighbor selection is claimed to match optimal end-to-end rates, but the full text is about dark photon searches, not wireless routing.
