Hierarchy of approximations for describing quantum light from high-harmonic generation: A Fermi-Hubbard model study
Christian Saugbjerg Lange, Lars Bojer Madsen
The quantum optical description of high-order harmonic generation where both the electrons of the generating medium and the driving and generated light fields are described quantum…
Beyond Electric-Dipole Treatment of Light-Matter Interactions in Materials: Nondipole Harmonic Generation in Bulk Si
Simon Vendelbo Bylling Jensen, Nicolas Tancogne-Dejean, Angel Rubio +1
A beyond electric-dipole light-matter theory is needed to describe emerging X-ray and THz applications for characterization and control of quantum materials but inaccessible as non…
Many-body effects on high-harmonic generation in Hubbard ladders
Yuta Murakami, Thomas Hansen, Shintaro Takayoshi +2
We show how many-body effects associated with background spin dynamics control the high-harmonic generation (HHG) in Mott insulators by analyzing the two-leg ladder Hubbard model.…
Intra- and intercycle analysis of intraband high-order harmonic generation
Asbjørn Tornøe Andersen, Simon Vendelbo Bylling Jensen, Lars Bojer Madsen
We study intraband high-order harmonic generation arising from a band-gap material driven by a linearly polarized laser field. We factorize the intraband high-order harmonic-genera…
Noninteger high-harmonic generation from extended correlated systems
Christian Saugbjerg Lange, Thomas Hansen, Lars Bojer Madsen
The spectra produced by high-harmonic generation (HHG) typically exhibit well-defined peaks at odd integers times the laser frequency. However, in recent investigations of HHG from…
Scattering of ultrashort electron wave packets: optical theorem, differential phase contrast and angular asymmetries
Yuya Morimoto, Lars Bojer Madsen
Recent advances in electron microscopy allowed the generation of high-energy electron wave packets of ultrashort duration. Here we present a non-perturbative S-matrix theory for sc…
