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…
