A squeezing protocol is proposed for nuclear spin ensembles coupled to superconducting circuits to achieve up to 48 dB squeezing and enhance superradiant interactions for relic detection.
In F-theory GUTs, non-universal ALPs induced by hypercharge flux satisfy g_aγ/m_a well below the QCD axion prediction when gauge couplings unify near the string scale.
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.
A review deriving couplings, noise spectra, SNRs, and quantum techniques like squeezing for detectors in dark matter, GW, and mechanical sensor experiments.
