Abstract
1st Part: Cavity quantum electrodynamics (CQED) serves as an elegant model for achieving strong coupling between light and matter. In this talk, we will theoretically demonstrate a novel way of controlling the reflectance of an atomic mirror and the finesse of a cavity [1]. Also, an application of manipulating the quasi-1D matter wave emitting superradiance when transversely flying through the atomic cavity will be presented.
2nd Part: We envisage for the first time an optomechanical system that bridges optical photons and x-rays with the aim to control the latter. The x-ray-optical interface system comprises of an optomechanical cavity and a movable microlever interacting with both an optical laser and with x-rays via resonant nuclear scattering [2]. We show that x-ray absorption spectra of nuclei can be tuned optomechanically, which reveals, e.g., optomechanically induced transparency of x-rays.
