Theory of ultrafast processes with X-ray light

Nina Rohringer is Lead Scientist at DESY and Professor of Physics at the University of Hamburg. Her research interests include the fundamental processes of the interaction of ultrafast pulses of X-ray free-electron lasers with matter. X-ray free-electron lasers, such as FLASH at DESY and the European XFEL in Schenefeld, are sources of radiation in the X-ray range that produce high-intensity pulses of few-femtoseconds duration and that are used to study the electronic structure of matter. The ultrashort pulse duration of these sources also allows time-resolved studies of the electron and core motion.

A special focus of Nina Rohringer's research group is the investigation of stimulated emission processes in the X-ray range, e.g. amplification of X-rays by stimulated emission or scattering at atomic transitions, as well as non-linear processes initiated by more than one X-ray photon. Advances in these investigations will ultimately lead to the development of new non-linear spectroscopic and imaging methods with X-rays to provide information about the concerted motion of electrons and nuclei in physical and chemical processes (such as phase transformation, chemical reaction, catalysis, photosynthesis, etc.).
