abstract

A novel method for extending frequency frontier in gravitational wave observations is proposed. It is shown that gravitational waves can excite a magnon. Thus, gravitational waves can be probed by a graviton-magnon detector which measures resonance fluorescence of magnons. Searching for gravitational waves with a wave length $\lambda$ by using a ferromagnetic sample with a dimension $l$, the sensitivity of the graviton-magnon detector reaches spectral densities, around $5.4 \times 10^{-22} \times (\frac{l}{\lambda /2\pi})^{-2} \ [{\rm Hz}^{-1/2}]$ at 14 GHz and $8.6 \times 10^{-21} \times (\frac{l}{\lambda /2\pi})^{-2} \ [{\rm Hz}^{-1/2}]$ at 8.2 GHz, respectively.

  1. Binary gravitational waves as probes of quantum graviton states

    gr-qc 2025-10 reject novelty 6.0 of 10

    Gravitational waves from binaries can, in principle, carry sub-Poissonian graviton statistics inherited from a squeezed primordial vacuum, offering a new signature of quantum gravity.

  2. Gravitational Photon Polarization Twist to Probe the Early Universe and the Galactic Center

    hep-ph 2025-07 conditional novelty 6.0 of 10

    A long-baseline laser pulse whose polarization is twisted by gravitational waves could detect galactic-center pulsar and early-universe gravitational wave backgrounds.

  3. High-Frequency Gravitational Waves on BREAD

    hep-ph 2025-05 conditional novelty 6.0 of 10

    BREAD with single photon detectors could detect high-frequency gravitational waves at 0.05 to 200 THz, with projected strains as low as 1e-25 at 200 THz.

  4. Toward graviton detection via photon-graviton quantum state conversion

    quant-ph 2025-07 conditional novelty 4.0 of 10

    Photon-to-graviton conversion in a magnetic field is shown to be enhanced by squeezed photon states and by the squeezed vacuum of primordial gravitational waves, with entanglement generation proposed as a quantum signature.
