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…
Light-induced nonequilibrium response of the superconducting cuprate LaSrCuO
Hiroaki Niwa, Naotaka Yoshikawa, Kaito Tomari +4
We report the dynamics of the cuprate superconductor LaSrCuO () after intense photoexcitation utilizing near-infrared (800 nm) optical pump-terahertz pr…
Charge carrier dynamics of FeSe thin film investigated by terahertz magneto-optical spectroscopy
Naotaka Yoshikawa, Masayuki Takayama, Naoki Shikama +4
We performed terahertz magneto-optical spectroscopy of FeSe thin film to elucidate the charge carrier dynamics. The measured diagonal (longitudinal) and off-diagonal (Hall) conduct…
Interband resonant high-harmonic generation by valley polarized electron-hole pairs
Naotaka Yoshikawa, Kohei Nagai, Kento Uchida +4
We demonstrated nonperturbative high harmonics induced by intense mid-infrared light up to 18th order that well exceed the material bandgap in monolayer transition metal dichalcoge…
Phase-resolved Higgs response in superconducting cuprates
Hao Chu, Min-Jae Kim, Kota Katsumi +26
In high energy physics, the Higgs field couples to gauge bosons and fermions and gives mass to their elementary excitations. Experimentally, such couplings can be inferred from the…
