Enhanced high-order harmonics through periodicity breaks: from backscattering to impurity states
Chuan Yu, Ulf Saalmann, Jan M. Rost
Backscattering of delocalized electrons has been recently established [Phys. Rev. A 105, L041101 (2022)] as a mechanism to enhance high-order harmonic generation (HHG) in periodic…

High harmonics from backscattering of delocalized electrons
Chuan Yu, Ulf Saalmann, Jan M. Rost
It is shown that electron backscattering can enhance high-harmonic generation in periodic systems with broken translational symmetry. Paradigmatically, we derive for a finite chain…

Crystal-momentum-resolved contributions to multiple plateaus of high-order harmonic generation from band-gap materials
Chuan Yu, Hossein Iravani, Lars Bojer Madsen
We study the crystal-momentum-resolved contributions to the high-order harmonic generation (HHG) in band-gap materials, and identify the relevant initial crystal momenta for the fi…
