Quantum optics model mapping for thin-film x-ray cavities — •Julien Spitzlay1, Hanns Zimmermann1,2, Fabian Richter1, and Adriana Pálffy1 — 1Julius-Maximilians-Universität Würzburg — 2Universität der Bundeswehr München
Thin-film cavities with one or several embedded layers of Mössbauer nuclei are promising platforms for the quantum control of x-ray photons. At grazing incidence, incoming resonant x-rays couple evanescently to the cavity, while the resulting cavity field drives the nuclear transitions. Several quantum optics models have been developed in the past decade to describe the resonant x-ray scattering in these nanostructures, for instance a cavity QED model [1] or an ab-initio formalism based on the electromagnetic Green’s function [2,3].
In this work we investigate parallels between the x-ray thin-film cavity models and well-known quantum optics models for coherent phenomena in few-level systems such as electromagnetically induced transparency (EIT) or Autler-Townes-Splitting (ATS). The aim is to identify parameter regimes where thin-film x-ray cavities can display a behaviour reminiscent to these phenomena and the relations between the coupling constants of the respective underlying quantum optics models.
