The emerging application of attosecond techniques to molecular systems allows the role of
electronic coherence in the control of chemical reactions to be investigated. Prompt …

This paper has been prepared by the Symphony collaboration (University of Warsaw,
Uniwersytet Jagielloński, DESY/CNR and ICFO) on the occasion of the 25th anniversary of …

The ultrafast motion of electrons and holes after light-matter interaction is fundamental to a
broad range of chemical and biophysical processes. We advanced high-harmonic …

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 …

Photoelectron holography constitutes a powerful tool for the ultrafast imaging of matter, as it
combines high electron currents with subfemtosecond resolution, and gives information …

We determine the ionization time in tunneling ionization by an elliptically polarized light
pulse relative to its maximum. This is achieved by a full quantum propagation of the electron …

Quantum particles can penetrate potential barriers by tunnelling. If that barrier is rotating, the
tunnelling process is modified,. This is typical for electrons in atoms, molecules or solids …

A review is presented of the rescattering plateau in laser-induced above-threshold ionization
and its various features as they were discovered over time. Several theoretical explanations …

Attosecond physics offers new insights into ultrafast quantum phenomena involving electron
dynamics on the fastest measurable timescales. The rapid progress in this field enables us …
