Prominent Dimensional Effects on High-order Harmonic Generation in Strongly Correlated Electron Systems
Kento Uchida, Shintaro Takayoshi, Yuta Murakami +6
Dimensionality strongly affects elementary excitations in correlated quantum materials, yet its impact on extreme nonlinear optical responses remains largely unexplored. Here, we c…
High harmonic interferometer:For probing sub-laser-cycle electron dynamics in solids
K. Uchida, K. Tanaka
High harmonic emissions from crystalline solids contain rich information on the dynamics of electrons driven by intense infrared laser fields and have been intensively studied owin…
Ultrafast electron-electron scattering in metallic phase of 2H-NbSe probed by high harmonic generation
K. S. Takeda, K. Uchida, K. Nagai +2
Electron-electron scattering on the order of a few to tens of femtoseconds plays a crucial role in the ultrafast electron dynamics of conventional metals. When mid-infrared light i…
Anomalous temperature dependence of high-harmonic generation in Mott insulators
Yuta Murakami, Kento Uchida, Akihisa Koga +2
We reveal the crucial effect of strong spin-charge coupling on high-harmonic generation (HHG) in Mott insulators. In a system with antiferromagnetic correlations, the HHG signal is…
Exciton-coherence generation through diabatic and adiabatic dynamics of Floquet state
Kento Uchida, Satoshi Kusaba, Kohei Nagai +2
Floquet engineering of electronic systems is a promising way of controlling quantum material properties on an ultrafast time scale. So far, the energy structure of Floquet states i…
Effect of incoherent electron-hole pairs on high harmonic generation in an atomically thin semiconductor
Kohei Nagai, Kento Uchida, Satoshi Kusaba +3
High harmonic generation (HHG) in solids reflects the underlying nonperturbative nonlinear dynamics of electrons in a strong light field and is a powerful tool for ultrafast spectr…
