Using time-dependent density-functional theory, high-harmonic generation (HHG) is studied
in one-dimensional structures of sizes from a single nucleus up to hundreds of nuclei. The …

We explore the significance of laser-induced correlation effects for high-order harmonic
generation (HHG) in a linear chain model of a generic band gap material for both single-IR …

Few-electron atoms interacting with electromagnetic fields provide for privileged scenarios
for disentangling elemental correlation mechanisms. We demonstrate that high-order …

We present a study of nonsequential double-recombination (NSDR) high-harmonic
generation (HHG) in a molecularlike system. We have calculated the HHG spectrum for a …

Contributions of the pre-ionized H 2 (PI-H 2) and ionized ${{\rm {H}}} _ {2}^{+} $ subsystems
of the two-electron H 2 system to its high-order harmonic generation in eight-cycle sin 2-like …

This book proposes a new theory about the neo-classical style in music. The Danish
emeritus professor Finn Egeland Hansen has chosen three different composers-the French …

This progress report is submitted for my qualifying exam at Aarhus University. This report
presents the work I have performed in the past two years where chapter 4 is a slightly …
