Research on isolated attosecond pulses (IAPs) based on high-order harmonic generation
changed substantially around 2010. Before then, the Ti: sapphire laser was the de facto …

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 …

Femtosecond mode-locked lasers producing visible/infrared frequency combs have steadily
advanced our understanding of fundamental processes in nature. For example, optical …

Photoionization is one of the fundamental light-matter interaction processes in which the
absorption of a photon launches the escape of an electron. The time scale of this process …

Photoionisation time delays carry structural and dynamical information on the target system,
including electronic correlation effects in atoms and molecules and electron transport …

Electronic dynamics in liquids are of fundamental importance, but time-resolved experiments
have so far remained limited to the femtosecond time scale. We report the extension of …

In ultrafast spectroscopy, the temporal resolution of time-resolved experiments depends on
the duration of the pump and probe pulses, and on the control and characterization of their …

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 …

The Hall response can be dramatically different from its quantized value in materials with
broken inversion symmetry. This stems from the leading Hall contribution beyond the linear …

In this Colloquium, the wave-function-based multiconfigurational time-dependent Hartree
approaches to the dynamics of indistinguishable particles (MCTDH-F for fermions and …
