Pulse-Duration Control of Subcycle Multiband Electron Dynamics Extends the High-Harmonic Cutoff in a Light-Driven Insulator
Hortense Allegre, Simon V. B. Jensen, Joseph J. Broughton +7
We demonstrate pathway-selective control of extreme-ultraviolet high-harmonic generation by jointly tuning laser pulse duration ( - fs) and intensity ( - TW/cm$^2…
Extreme Ultraviolet High-Harmonic Interferometry of Excitation-Induced Bandgap Dynamics in Solids
Lisa-Marie Koll, Simon Vendelbo Bylling Jensen, Pieter J. van Essen +9
Interferometry is a fundamental technique in physics, enabling precise measurements through the interference of waves. High-harmonic generation (HHG) in solids has emerged as a pow…
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…
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…
High-harmonic spectroscopy of strongly bound excitons in solids
Simon Vendelbo Bylling Jensen, Lars Bojer Madsen, Angel Rubio +1
We explore the nonlinear response of ultrafast strong-field driven excitons in a one-dimensional solid with ab initio simulations. We demonstrate from our simulations and analytica…
Uncovering Extreme Nonlinear Dynamics in Solids Through Time-Domain Field Analysis
Phillip D. Keathley, Simon V. B. Jensen, Matthew D. Yeung +2
Time-domain analysis of harmonic fields with sub-cycle resolution is now experimentally viable due to the emergence of sensitive, on-chip techniques for petahertz-scale optical-fie…
Correlation effects in high-harmonic generation from finite systems
Thomas Hansen, Simon Vendelbo Bylling Jensen, Lars Bojer Madsen
Using the Hubbard model we study how the process of high-order harmonic generation (HHG) is modified by beyond mean-field electron-electron correlation for both finite and bulk sys…
Propagation time and nondipole contributions to intraband high-harmonic generation
Simon Vendelbo Bylling Jensen, Lars Bojer Madsen
Applying the semiclassical model, we identify two connected effects in intraband high-harmonic generation (HHG): (1) propagation time from the point of emission at the source to th…
Edge-state and bulk-like laser-induced correlation effects in high-harmonic generation from a linear chain
Simon Vendelbo Bylling Jensen, Lars Bojer Madsen
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-…
Edge-state-induced correlation effects in two-color high-harmonic generation
Simon Vendelbo Bylling Jensen, Hossein Iravani, Lars Bojer Madsen
We show that two-color high-harmonic spectroscopy can reveal finite-size and edge-state-induced dynamic electron correlation effects in a generic nanostructured band-gap material.…
