Quantum Optics with X-Rays

Former Independent Max Planck Research Group - Dr. Nina Rohringer

Welcome to the website of the independent Max Planck Research Group focusing on the interaction of high-intensity X-rays with atomic and molecular gases.

We are studying fundamental interactions of ultrashort high-intensity X-ray pulses from X-ray free-electron lasers (XFELs) with matter. A special focus of our research group is to investigate stimulated X-ray emission processes in atomic and molecular gases. Within this context, we develop new XFEL-pumped X-ray lasers, which are based on the amplification of X-ray radiation on electronic inner-shell transitions in atoms and molecules.

Furthermore, we investigate stimulated inelastic X-ray scattering in molecules, to unravel the importance of electronic and vibrational dynamics induced by the interaction with high-intensity X-ray radiation. Our research is tailored to ultimately develop new nonlinear X-ray spectroscopic techniques to probe, for example, electronic and vibrational coherences in light-induced chemical reactions.
