Two We develop advanced attosecond technologies to investigate the light-activated dynamics of matter with extreme time resolution. In particular, the main goal of our research is to track and ideally control the electronic motion in systems of increasing complexity, from simple molecules to biochemically relevant molecules and nanoparticles. For reference, an attosecond is one quintillionth of a second. If we scale that up, there are as many attoseconds in one second as there are seconds in 31.7 billion years. It's a mind-bogglingly 2020-08-21 2007-08-10 We describe the recent emergence of attosecond science, assessing the present state of the art and discussing several recent examples where attosecond electron dynamics has been studied in atomic and molecular systems.

In the last 15 years impressive advances have been obtained from both the experimental and theoretical points of view. 2020-11-30 · The subcycle interaction of light and electrons has been one of the key frontiers in free-electron lasers, attosecond science and dynamical investigation of matter. Attosecond pulses are produced in a process called high-order harmonic generation, in which a short, intense laser pulse interacts with atoms or molecules in a highly nonlinear process, leading to the generation of high-order frequencies of the fundamental laser with a large spectral bandwidth, supporting pulses with attosecond duration.
