Inverse design approach to x-ray quantum optics with Mössbauer nuclei in cavities — Oliver Diekmann1,2, Dominik Lentrodt1,3, and •Jörg Evers1 — 1Max Planck Institute for Nuclear Physics, Heidelberg, Germany — 2Institute for Theoretical Physics, Vienna University of Technology, Austria — 3Physikalisches Institut, Albert-Ludwigs-Universität Freiburg, Freiburg, Germany
Nanometer-sized thin-film cavities containing ensembles of Mössbauer nuclei have been demonstrated to be a rich platform for x-ray quantum optics [1]. At low excitation, these systems allow one to implement tunable artificial quantum systems at hard x-ray energies. However, until recently, the inverse problem of determining a cavity structure which realizes a desired level scheme remained unsolved. In this talk, I will introduce the inverse design and develop a comprehensive optimization which allows one to determine optimum cavity systems realizing few-level schemes with desired properties [2,3]. Using this approach, the accessible parameter spaces of artificial multi-level systems can be characterized. Further, I will discuss a number of qualitative insights into x-ray photonic environments for nuclei that will likely impact the design of future x-ray cavities and thereby improve their performance.
