Advances in attosecond science have led to a wealth of important discoveries in atomic,
molecular, and solid-state physics and are progressively directing their footsteps toward …

The need for accurate calculations on atoms and diatomic molecules is motivated by the
opportunities and challenges of such studies. The most commonly used approach for all …

Context. Vacuum-ultraviolet (VUV) photons are important drivers of chemical processes in
space. Thus, it is important to accurately characterize and constrain photorates in different …

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

With the advent of attosecond light pulses at the beginning of this century, the possibility to
perform real‐time observations of electron motion in molecules has spurred impressive …

RMT is a programme which solves the time-dependent Schrödinger equation for general,
multielectron atoms, ions and molecules interacting with laser light. As such it can be used to …

We present a comprehensive theoretical study of valence-shell photoionization of the CO2
molecule by using the XCHEM methodology. This method makes use of a fully correlated …

The study of onset and decay, as well as control of ultrafast quantum coherence in many-
electron systems is in the focus of interest of attosecond physics. Interpretation of attosecond …

The perceived dichotomy between analytical and ab initio approaches to theory in
attosecond science is often seen as a source of tension and misconceptions. This Topical …

Advances in coherent light sources and development of pump–probe techniques in recent
decades have opened the way to study electronic motion in its natural time scale. When an …
