The observation of acoustically induced transparency has demonstrated the potential for suppressing photon absorption and synchronizing transmitted photons with material vibrations. By extending this phenomenon to a novel phase-locked regime, there is potential for developing an acoustically controlled interface between hard x-ray photons and nuclear ensembles, utilizing the advantages of synchrotron Mossbauer sources.
The induced transparency of opaque medium for resonant electromagnetic radiation is a powerful tool for manipulating the field-matter interaction. Various techniques to make different physical systems transparent for radiation from microwaves to x-rays were implemented. Most of them are based on the modification of the quantum-optical properties of the medium under the action of an external coherent electromagnetic field. Recently, an observation of acoustically induced transparency (AIT) of the Fe-57 absorber for resonant 14.4-keV photons from the radioactive Co-57 source was reported. About 150-fold suppression of the resonant absorption of photons due to collective acoustic oscillations of the nuclei was demonstrated. In this paper, we extend the AIT phenomenon to a novel phase-locked regime, when the transmitted photons are synchronized with the absorber vibration. We show that the advantages of synchrotron Mossbauer sources such as the deterministic periodic emission of radiation and controlled spectral-temporal characteristics of the emitted photons along with high-intensity photon flux in a tightly focused beam, make it possible to efficiently implement this regime, paving the way for the development of the acoustically controlled interface between hard x-ray photons and nuclear ensembles.
