XUV Attosecond Photoionization and Related Ultrafast Processes in Diatomic and Large Molecules
Abstract
New means of inducing and probing in real-time charge dynamics and energy flow in molecules have evolved with progresses made in laser technology and secondary sources. One significant example is the light source based on high harmonic generation (HHG). Such a source typically allows the production of extreme ultraviolet (XUV) radiations temporally confined in very short pulses down to a few tens of femtoseconds and even attosecond duration. This naturally offers new opportunities to study extremely fast processes in very excited molecular species and to track dynamics down to the ultimate time scale of electronic motion. This chapter summarizes recent results obtained in simple and complex molecular species using these short XUV pulses. It demonstrates the potential impact of pump-probe XUV science in molecular physics, chemistry, plasmonic or astrochemistry. Hints of dynamics below 1 fs in pump-probe experiments are already observed in increasingly large systems showing the way to chemistry on attosecond time scale.
