Few-Photon Quantum Optics with Nuclei in Thin-Film Cavities — •Paolo Longo, Christoph H. Keitel, and Jörg Evers — Max-Planck-Institut für Kernphysik (MPIK), 69117 Heidelberg

Recent activities in the field of X-ray quantum optics [1–4] address, for example, the problem of single-photon superradiance in an extended sample of ⁵⁷Fe nuclei embedded in a thin-film cavity [5]. In the near future, new light sources [6] will further boost the study of such collective phenomena and eventually go beyond the level of at most one photon. Based on first principles and our earlier work on collective emission [7], we develop a theoretical description for the study of X-ray few-photon quantum optics, revealing the collective atomic states’ properties in conjunction with the resulting far-field signatures.
