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 …

Attosecond metrology has so far largely remained limited to titanium: sapphire lasers
combined with an active stabilization of the carrier-envelope phase (CEP). These sources …

Recently two emerging areas of research, attosecond and nanoscale physics, have started
to come together. Attosecond physics deals with phenomena occurring when ultrashort laser …

The generation of extremely short isolated attosecond pulses requires both a broad spectral
bandwidth and control of the spectral phase. Rapid progress has been made in both …

The accurate measurement of time lies at the heart of experimental science, and is relevant
to everyday life. Extending chronoscopy to ever shorter timescales has been the key to …

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 …

We bring together two topics that, until now, have been the focus of intense but non-
overlapping research efforts. The first concerns high-harmonic generation in solids, which …

The transfer of charge at the molecular level plays a fundamental role in many areas of
chemistry, physics, biology and materials science. Today, more than 60 years after the …
