Control of high-harmonic generation by tuning the electronic structure and carrier injection
Hiroyuki Nishidome, Kohei Nagai, Kento Uchida +4
High-harmonic generation (HHG), which is generation of multiple optical harmonic light, is an unconventional nonlinear optical phenomenon beyond perturbation regime. HHG, which was…
Dynamical symmetry of strongly light-driven electronic system in crystalline solids
Kohei Nagai, Kento Uchida, Naotaka Yoshikawa +3
The Floquet state, which is a periodically and intensely light driven quantum state in solids, has been attracting attention as a novel state that is coherently controllable on an…
Inherent Limit to Coherent Phonon Generation under Non-Resonant Light Field Driving
Kento Uchida, Kohei Nagai, Naotaka Yoshikawa +1
Coherent manipulation of quasi-particles is a crucial method to realize ultrafast switching of the relating macroscopic order. In this letter, we studied coherent phonon generation…
