Photoionization dynamics

Attosecond pulses created by high harmonic generation (HHG) in gases allow us to study fundamental light-matter interaction processes with novel experimental techniques. The ultrashort light pulse leads to the creation of a wave packet that can be exploited to investigate attosecond dynamics in ionized systems. We apply interferometric techniques to access the correlated multi-electron dynamics in complex systems aiming to monitor in real time charge migration/transfer.
