Enhanced high-order harmonic generation in donor-doped band-gap materials
Chuan Yu, Kenneth K. Hansen, Lars Bojer Madsen
We find that a donor-doped band-gap material can enhance the overall high-order harmonic generation (HHG) efficiency by several orders of magnitude, compared with undoped and accep…
Finite-system effects on high-harmonic generation: from atoms to solids
Kenneth K. Hansen, Dieter Bauer, Lars Bojer Madsen
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…
High-harmonic generation in solids with and without topological edge states
Dieter Bauer, Kenneth K. Hansen
High-harmonic generation (HHG) in the two topological phases of a finite, one-dimensional, periodic structure is investigated using a self-consistent time-dependent density functio…
High-order harmonic generation in solid slabs beyond the single active electron
Kenneth K. Hansen, Tobias Deffge, Dieter Bauer
High-harmonic generation by a laser-driven solid slab is simulated using time-dependent density functional theory. Multiple harmonic plateaus up to very high harmonic orders are ob…
Non-Sequential Double Recombination High Harmonic Generation in Molecular-like Systems
Kenneth K. Hansen, Lars Bojer Madsen
We present a study of non-sequential double recombination (NSDR) high harmonic generation (HHG) in a molecular-like system. Using a Coulomb-corrected three-step model we are able t…
Same Period Emission and Recombination in Non-Sequential Double Recombination High-Harmonic Generation in H
Kenneth K. Hansen, Lars Bojer Madsen
Non-sequential double recombination (NSDR) high-order harmonic generation (HHG) is studied in a molecular system. We observe a unique molecular two-electron effect with a character…
