TLDR
In this article, high-order harmonic generation for molecules in linearly polarized laser pulses by numerical solution of the Schr\"odinger equation was studied and maxima and minima due to intramolecular interference were found in the dependence of the harmonic intensities on the internuclear distance and on the orientation of the molecules.Abstract:
We study high-order harmonic generation for ${\mathrm{H}}_{2}^{+}$ and ${\mathrm{H}}_{2}$ model molecules in linearly polarized laser pulses by numerical solution of the Schr\"odinger equation. Maxima and minima due to intramolecular interference are found in the dependence of the harmonic intensities on the internuclear distance and on the orientation of the molecules. These extrema can be approximately predicted by regarding them as the result of interference between two radiating point sources located at the positions of the nuclei.read more

TL;DR: In this paper, the effects of signal modulations on the molecular high-order harmonic generations in molecular high order harmonic generations have been theoretically investigated, and it is found that with the introduction of the XUV pulse, due to the absorption of the extra XUV photons in the recombination process, multi-plateaus on the harmonic spectra, separated by XUV photon energy can be found.

Doping effects in high-harmonic generation from correlated systems
TL;DR: In this paper , a quasiparticle-based doublon-holon model was used to study high-harmonic generation from doped, correlated materials, and it was shown that in the high-U$ limit, antiferromagnetic ordering becomes increasingly unlikely with increasing doping rates and explain an associated drop in high-order harmonics relative to the case of half filling.
