Stochastic gravitational wave background from the early Universe has a cut-off frequency close to 100 MHz, due to the horizon of the inflationary phase. To detect gravitational waves at such frequencies, resonant electromagnetic cavities are very suitable. In this work, we study the frequency sensitivity of such detectors, and show how we could use them to probe this cut-off frequency and also the energy density per frequency of this stochastic background. This paper paves the way for further experimental studies to probe the most ancient relic of the Universe.

  1. High-frequency gravitational waves from axion inflation in the weak-backreaction regime

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Even in the weak-backreaction regime, axion inflation produces high-frequency primordial gravitational waves many orders of magnitude above the vacuum spectrum, peaking around MHz–GHz.

  2. Gravitational waves from self-resonance during reheating with a quantum-corrected inflaton potential

    hep-ph 2026-07 conditional novelty 6.0 of 10

    A Coleman-Weinberg correction that cancels the inflaton's quadratic term at the potential minimum triggers quartic self-resonance and a peaked GW background at 10^8-10^10 Hz; a negative quadratic term instead gives a ...

  3. Leptogenesis with sub-electroweak-scale reheating temperature

    hep-ph 2026-07 conditional novelty 6.0 of 10

    Leptogenesis remains viable for reheating temperatures below sphaleron freeze-out in three perturbative monomial-inflaton scenarios, with blue-tilted primordial GWs as a potential probe.

  4. Constraining the inflaton potential with gravitational waves from oscillons

    astro-ph.CO 2026-01 conditional novelty 6.0 of 10

    The rapid decay of an oscillon-dominated post-inflation phase produces induced gravitational waves strong enough that the BBN/CMB bound on relativistic species excludes significant regions of inflaton mass–coupling pa...

  5. Complementary Probes of Warped Extra Dimension: Colliders, Gravitational Waves and Primordial Black Holes from Phase Transitions

    hep-ph 2025-02 conditional novelty 6.0 of 10

    In Randall-Sundrum warped extra dimension models, the supercooled radion phase transition can form primordial black holes that account for all of dark matter for IR scales 10 TeV to 10^4 TeV, with correlated gravitati...

  6. Magnetic monopoles and high frequency gravitational waves from quasi-stable strings

    hep-ph 2026-03 conditional novelty 4.0 of 10

    SO(10) breaking through flipped SU(5) or Pati-Salam subgroups can produce GUT monopoles from merging monopole-antimonopole pairs, while the intervening quasi-stable strings emit gravitational waves from Hz to kHz.

  7. C-parity, magnetic monopoles and higher frequency gravitational waves

    hep-ph 2025-02 conditional novelty 4.0 of 10

    The C-string-wall network from SO(10) breaking with unbroken C-parity produces a gravitational wave background peaking between 100 Hz and 100 kHz for intermediate breaking scales around 10^10 to 10^12 GeV.
