Cím: XUV induced ultrafast mechanisms in molecular structures: from attosecond
physics … to astrochemistry

Absztrakt: Short XUV pulses combine two advantages for physicists and
chemists, which are motivating the development of intense research programs
worldwide. First, high-energy photons allow the generation of highly excited
species and second, short duration gives access to ultrafast phenomena in
realtime.
In molecules, short XUV pulses can trigger complex dynamics that can be
followed in real-time using pump-probe schemes, down to the attosecond time-
scale. Due to high photon energy excitation, induced processes imply
interaction between all the particles constituting the molecule (so-called:
electron correlation, non-adiabatic couplings etc…). Therefore a theoretical
description requires state-of-the-art many-body quantum theories.
Being able to perform such “realtime” experiments, combined with accurate
theoretical quantum description in increasingly complex systems is a major
challenge for the development of the emerging field of attosecond molecular
physics. Although challenging, it is expected that this research activity
would have major impact in other fields and would nourish analytical
chemistry, molecular electronics, astrophysics and fundamental aspects of
quantum mechanics in general.
