stopping x-ray pulses in a thin-film cavity — •xiangjin kong and adriana pálffy — Max Planck Institute for Nuclear Physics, Saupfercheckweg 1, D-69117 Heidelberg, Germany

Recent years have witnessed the commissioning of coherent x-ray sources opening the new field of x-ray quantum optics [1]. While not yet as advanced as its optical counterpart, x-ray quantum optics may enable coherent control of x-rays, with potential applications for the fields of metrology, material science, quantum information, biology and chemistry. The desirable properties of x-rays are deeper penetration, better focus, no longer limited by an inconvenient diffraction limit as for optical photons, correspondingly spatial resolution, robustness, and the large momentum transfer they may produce. A promising platform for x-ray control are thin-film planar x-ray cavities [2] with embedded layers containing nuclei with a transition resonant to the x-ray pulse.

Here, we demonstrate from the theory side that a spectrally narrow x-ray pulse can be mapped and stored as nuclear coherence through a mechanism reminding of electromagnetically induced transparency in a thin film planar x-ray cavity. The storage time can reach approximate hundred nanoseconds [3]. We anticipate this setup can become a versatile tool for control of spectrally narrow x-ray pulses.
