From: Optomechanically induced transparency of x-rays via optical control
Sketch of the optomechanical interface between optical and x-ray photons. (a) The optical cavity is composed of a fixed mirror and a movable microlever whose oscillating frequency ω m can be controlled. A layer containing Mössbauer nuclei that can resonantly interact with x-rays is embedded in the tip of the microlever. (b) Level scheme of the effective nuclear harmonic oscillator. Lower (upper) three states correspond to the ground (excited) state g (e) while v (n) denotes the number of fluctuated cavity photons (number of phonons). Vertical green arrows depict the x-ray absorption by nuclei (with x-ray detuning Δ), and red diagonal arrows illustrate the beam splitter interaction between cavity photons and the microlever’s mechanical motion. The full yellow ellipse indicates the initial state of the system.
