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 …

Attosecond pulses are generated by a macroscopic number of ionizing atoms interacting
with a focused laser pulse, via the process of high harmonic generation. The physics of their …

Photoemission from atoms is assumed to occur instantly in response to incident radiation
and provides the basis for setting the zero of time in clocking atomic-scale electron motion …

Ionization is the dominant response of atoms and molecules to intense laser fields and is at
the basis of several important techniques, such as the generation of attosecond pulses that …

A strong laser field may tunnel ionize a molecule from several orbitals simultaneously,
forming an attosecond electron–hole wavepacket. Both temporal and spatial information on …

This tutorial presents an introduction to the interaction of light and matter on the attosecond
timescale. Our aim is to detail the theoretical description of ultra-short time delays and to …

We review the first ten years of attosecond science with a selection of recent highlights and
trends and give an outlook on future directions. After introducing the main spectroscopic …

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 …

Infrared and visible light beams carrying orbital angular momentum (OAM) are currently
thoroughly studied for their extremely broad applicative prospects, among which are …

We present an interferometric pump-probe technique for the characterization of attosecond
electron wave packets (WPs) that uses a free WP as a reference to measure a bound WP …
