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 …

The milestones of attosecond optics research in the last 15 years are briefly reviewed, and
the latest trends in applications in gaseous and condensed matter are introduced. An …

We report on the energy dependence of the photoemission time delay from the single-
element layered dielectric HOPG (highly oriented pyrolytic graphite). This system offers the …

Recent experiments access the time-resolved photoelectron signal originating from plasmon
satellites in correlated materials and address their buildup and decay in real time. Motivated …

Relative phases of atomic above-threshold ionization wave packets were investigated in an
experiment [LJ Zipp, A. Natan, and PH Bucksbaum, Optica 1, 361 (2014) 10.1364/OPTICA …

This tutorial provides an overview on the theory of attosecond streaking, a pump-probe
scheme to extract timing information of ionization processes that has been widely used in …

The growing interest in using x-ray spectroscopy for refined materials characterization calls
for an accurate electronic-structure theory to interpret the x-ray near-edge fine structure. In …

After photon absorption, electrons from a dispersive band of a solid require a finite time in
the photoemission process before being photoemitted as free particles, in line with recent …
