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…
Attosecond-resolved probing of recolliding electron wave packets in liquids and aqueous solutions
Angana Mondal, Nicolas Tancogne-Dejean, George Trenins +8
High-harmonic spectroscopy (HHS) in liquids promises real-time access to ultrafast electronic dynamics in the native environment of chemical and biological processes. While electro…
Multi-plateau high-harmonic generation in liquids driven by off-site recombination
Angana Mondal, Ofer Neufeld, Tadas Balciunas +7
Non-perturbative high-harmonic generation (HHG) has recently been observed in the liquid phase, where it was demonstrated to have a different physical mechanism compared to gas and…
Correlations drive the attosecond response of strongly-correlated insulators
Romain Cazali, Amina Alic, Matthieu Guer +8
Attosecond spectroscopy of materials has provided invaluable insight into light-driven coherent electron dynamics. However, attosecond spectroscopies have so far been focused on we…
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…
