Sensing coherent phonon dynamics in solids with delayed even harmonics
Jinbin Li, Ulf Saalmann, Hongchuan Du +1
High harmonics have emerged as a powerful ultrafast probe of phonon dynamics and electron-phonon interactions in solids, with most studies focusing on odd harmonics. Here, in a pum…

Electron dynamics driven by light pulse derivatives
Qi-Cheng Ning, Ulf Saalmann, Jan M. Rost
We demonstrate that ultrashort pulses carry the possibility for a new regime of light-matter interaction with nonadiabatic electron processes sensitive to the envelope-derivative o…
