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 …

For over a century since the Nobel prize winning work by Einstein (1905 Ann. Phys. 17 132),
atomic photoionization was thought to be an instantaneous process. Recent experimental …

Attosecond metrology of atoms has accessed the time scale of the most fundamental
processes in quantum mechanics. Transferring the time-resolved photoelectric effect from …

Photoionization as a half-scattering process is not instantaneous. Usually, time delays in
photoionization are on the order of tens of attoseconds. In going from a single atom to a …

The photoelectric effect is not truly instantaneous but exhibits attosecond delays that can
reveal complex molecular dynamics,,,,,–. Sub-femtosecond-duration light pulses provide the …

Photoionization of atoms and molecules is one of the fastest processes in nature. The
understanding of the ultrafast temporal dynamics of this process often requires the …

Attosecond photoionization time delays reveal information about the potential energy
landscape that an outgoing electron wavepacket probes upon ionization. In this study, we …

In a seminal article, Fano predicts that absorption of light occurs preferably with increase of
angular momentum. We generalize Fano's propensity rule to laser-assisted photoionization …

Temporal delays extracted from photoionization phases are currently determined with
attosecond resolution by using interferometric methods. Such methods require special care …

Advancements in light engineering have led to the creation of pulsed laser sources capable
of delivering high-repetition-rate, high-power few-cycle laser pulses across a wide spectral …
