Program Description:
Ultrafast X-ray spectroscopy allows the study of light-matter interaction with unprecedented temporal and spatial resolution with the further advantages of being element-selective and oxidation- and spin-state specific. The investigation of the properties of core electrons at ultrafast time scales promises to enlighten the dynamics occurring in complex materials. I will present the results we obtained at the FERMI free electron laser, where we investigated ultrafast dynamics in chiral molecules by photoelectron circular dichroism, extending this approach to core-level photoionization. Furthermore, I will discuss the recent developments we implemented toward attosecond X-ray spectroscopy based on tabletop sources, such as a bright XUV source based on high-order harmonic generation in microchannels and a mid-IR driving source for harmonic spectroscopy.
