Intense ultrashort light pulses comprising merely a few wave cycles became routinely
available by the turn of the millennium. The technologies underlying their production and …

In this review, we will focus on the theoretical aspects in observing and controlling the
electronic dynamics in few-electron atoms and molecules by attosecond pulses in different …

The first book dedicated to this new and powerful computational method begins with a
comprehensive description of MCTDH and its theoretical background. There then follows a …

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

A strong laser field may tunnel ionize a molecule from several orbitals simultaneously,
forming an attosecond electron–hole wavepacket. Both temporal and spatial information on …

The emission of coherent XUV radiation from atomic or molecular gases exposed to intense
infrared laser pulses, known as high harmonic generation, is of paramount interest in atomic …

By analyzing accurate theoretical results from solving the time-dependent Schrödinger
equation of atoms in few-cycle laser pulses, we established the general conclusion that …

When molecules are subject to intense laser pulses, electrons can be detached, accelerated
and driven back to the molecule, resulting in electron–ion recollisions. Recolliding electrons …

Implementation of Dyson orbitals for coupled-cluster and equation-of-motion coupled-cluster
wave functions with single and double substitutions is described and demonstrated by …

We present an implementation of the time-dependent configuration-interaction singles
(TDCIS) method for treating atomic strong-field processes. In order to absorb the …
