AbstractUnder the local gravitational field, perturbations from high-frequency gravitational waves can cause a vertical shift of the Mossbauer resonance height. Considering a stationary scheme with the Ag-109 isotope, we demonstrate that the extremely high frequency precision in Mossbauer resonance allows for competitive gravitational wave sensitivity from KHz up to above MHz frequencies. Mossbauer resonance can offer a novel and small-sized alternative in the quest of multi-band gravitational wave searches.
