Rabi oscillations of x-ray radiation between two nuclear ensembles — Xiangjin Kong1, Johann Haber2, Ralf Röhlsberger2, and •Adriana Pálffy1 — 1Max-Planck-Institut für Kernphysik, Heidelberg — 2Deutsches Elektronen-Synchrotron DESY, Hamburg
The realization of the strong coupling regime between a single cavity mode and an electromagnetic resonance is one of the centerpieces of quantum optics. In this regime, the reversible exchange of a photon between the two components of the system leads to so-called Rabi oscillations [1]. Strong coupling was used in the optical and infrared regimes to produce non-classical states of light, enhance optical nonlinearities, and control quantum states for computing purposes.
Here, we report from the theory side on the first observation of Rabi oscillations of an x-ray photon between two resonant 57Fe-layers embedded in two coupled cavities [2]. The theoretical predictions for the observed oscillation are based on an effective Hamiltonian for the system, in which the two layers couple strongly. A sinusoidal beating in the system’s temporal evolution as signature of the Rabi oscillations, as well as the splitting of the nuclear resonances in the reflected light spectrum have been confirmed by experiment. These observations significantly advance the development of the new field of x-ray quantum optics.
