Since the first demonstration of the generation of attosecond pulses (1 as= 10− 18 s) in the
extreme-ultraviolet spectral region, several measurement techniques have been introduced …

Attosecond science offers formidable tools for the investigation of electronic processes at the
heart of important physical processes in atomic, molecular and solid-state physics. In the last …

Recent advances in the generation of well-characterized subfemtosecond laser pulses have
opened up unpredicted opportunities for the real-time observation of ultrafast electronic …

Photoemission of an electron is commonly treated as a one-particle phenomenon. With
attosecond streaking spectroscopy we observe the breakdown of this single active-electron …

Chiral light-matter interactions have been investigated for two centuries, leading to the
discovery of many chiroptical processes used for discrimination of enantiomers. Whereas …

We report measurements of energy-dependent photoionization delays between the two
outermost valence shells of N 2 O and H 2 O. The combination of single-shot signal …

The history and current status of the Keldysh theory of strong field ionization are reviewed.
The focus is on the fundamentals of the theory, its most important applications and those …

Resolving in time the dynamics of light absorption by atoms and molecules, and the
electronic rearrangement this induces, is among the most challenging goals of attosecond …

Attosecond metrology of atoms has accessed the time scale of the most fundamental
processes in quantum mechanics. Transferring the time-resolved photoelectric effect from …

Photoionization is one of the fundamental light-matter interaction processes in which the
absorption of a photon launches the escape of an electron. The time scale of this process …
