Key properties of quantum materials stem from dynamic interaction chains that connect
stable electronic quasiparticles through short-lived coherences, which are difficult to control …

Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

The microscopic valence electron density determines the optical, electronic, structural and
thermal properties of materials. However, current techniques for measuring this electron …

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 …

The past two decades have seen rapid developments in short-pulse X-ray sources, which
have enabled the study of nuclear and electronic dynamics by ultrafast X-ray spectroscopies …

High harmonic generation (HHG) in solids is investigated. We find that interband emission is
dominant for the midinfrared laser driver frequencies, whereas intraband emission …

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 motion of electrons on the atomic scale has been hidden from direct experimental
access until recently. We review the revolution in technology that opened the door to real …

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 …

Research on promising materials with good performance for detecting or removing the
potent greenhouse gas sulfur hexafluoride (SF 6) is critical for environmental preservation …
