Description

The piezoaxionic effect enables the conversion of axion-induced spin-dependent forces in polarized nuclei into measurable voltages within piezoelectric crystals. A heterodyne detection scheme is introduced in which controlled nuclear spin precession mixes the axion oscillation frequency with the nuclear Larmor frequency. This process generates sideband signals at shifted frequencies, allowing efficient scanning of axion masses by changing the applied magnetic field. This method offers a tunable, noise-resistant approach to probing QCD axion dark matter in the MHz to GHz frequency range.
