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…

Intraband and Interband Competition Drives Ultrafast Modulations of Indium Tin Oxide
Anthony C Harwood, Sean Z J Lim, T V Raziman +7
Transparent conducting oxides near their epsilon-near-zero frequency exhibit near-unity ultrafast modulations of the refractive index which have enabled the field of time-varying m…
