Design and control of quantum optical schemes at x-ray energies — Paolo Longo, Kilian P. Heeg, Christoph H. Keitel, and •Jörg Evers — Max Planck Institute for Nuclear Physics, Heidelberg

Modern synchrotron light sources and x-ray free electron lasers strive to continue the success story of optical lasers at hard x-ray energies. However, in contrast to the broad capabilities available in labs operating at optical frequencies, the implementation of laser-coupled quantum systems in the x-ray domain remains a challenge due to basic experimental limitations. In recent years, first steps to circumvent these limitations were taken by few experiments which demonstrated basic quantum optical effects at x-ray energies. However, systematic approaches to implement advanced quantum optical level schemes at x-ray energies are currently lacking, impeding further progress in the field.

Here, we present our progress towards such a systematic approach. Our basic idea is to tailor cooperative effects in large ensembles of nuclei in such a way that effectively, a single artificial quantum system is simulated with the desired properties. To achieve this goal, we consider nuclear ensembles embedded in an x-ray cavity as our model system.
