The ultrafast hole dynamics triggered by the photoexcitation of molecular targets is a highly
correlated process even for those systems, such as organic molecules, having a weakly …

We explore the capabilities offered by attosecond extreme ultraviolet and x-ray pulses that
can now be generated by free-electron lasers and high-order harmonic generation sources …

A wide range of ultrafast phenomena in various atomic, molecular and condense matter
systems is governed by electron dynamics. Therefore, the ability to image electronic motion …

Harnessing the optoelectronic response of organic semiconductors requires a thorough
understanding of the fundamental light-matter interaction that is dominated by the excitation …

Time-resolved momentum microscopy provides insight into the ultrafast interplay between
structural and electronic dynamics. Here we extend orbital tomography into the time domain …

Conical intersections are formed when 2 or more electronic states become degenerate and
give rise to ultrafast nonadiabatic processes such as radiation-less decay channels and …

Driven by recent developments in time-resolved photoemission spectroscopy, we extend the
successful method of photoemission orbital tomography (POT) to excitons. Our theory …

We propose an imaging technique to follow core-hole wave-packet oscillations in the
nitrogen molecule. In this scheme, an attosecond x-ray pulse core-ionizes the nitrogen …

A photofragmentation study of gas-phase indole (C8H7N) upon single-photon ionization at a
photon energy of 420 eV is presented. Indole was primarily inner-shell ionized at its nitrogen …

Optical manipulation of light is a highly relevant concept in modern solid-state physics and
its microscopic mechanisms are widely investigated. From this perspective, we discuss how …
