Nina Rohringer
Theory of ultrafast processes with X-ray light
Nina Rohringer's research interests include the fundamental processes of the interaction of ultrafast X-ray pulses of free-electron X-ray lasers with matter. Free-electron X-ray lasers, such as FLASH at DESY and the European XFEL, are sources of radiation in the X-ray range of the electromagnetic spectrum that produce high-intensity pulses of the duration of a few femtoseconds and are used to study the electronic structure of matter. The ultrafast pulse duration of these sources also allows time-resolved studies of the electron and core motion. A special focus of the research group is the study of stimulated emission processes in the X-ray range, e.g. amplification of X-ray radiation 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-radiation 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.) win.
