Generation of third-harmonic spin oscillation from strong spin precession induced by terahertz magnetic near fields
Zhenya Zhang, Fumiya Sekiguchi, Takahiro Moriyama +9
The ability to drive a spin system to state far from the equilibrium is indispensable for investigating spin structures of antiferromagnets and their functional nonlinearities for…
Diabatic Mechanisms of Higher-Order Harmonic Generation in Solid-State Materials under High-Intensity Electric Fields
T. Tamaya, A. Ishikawa, T. Ogawa +1
We theoretically investigate mechanisms of higher-order harmonic generation in solid-state materials under a high-intensity ac electric field. A new theoretical framework presented…
Higher-Order Harmonic Generation caused by Elliptically Polarized Electric Fields in Solid-State Materials
T. Tamaya, A. Ishikawa, T. Ogawa +1
We theoretically investigated the dependence of higher-order harmonic generation (HHG) in solid-state materials on the ellipticity of the electric field. We found that in the multi…
Sub-Cycle Optical Response Caused by Dressed State with Phase-Locked Wavefunctions
K. Uchida, T. Otobe, T. Mochizuki +7
The coherent interaction of light with matter imprints the phase information of the light field on the wavefunction of the photon-dressed electronic state. Driving electric field,…
Instantaneous Photon Drag Currents in Topological Insulators
Yoshito Onishi, Zhi Ren, Mario Novak +3
Topological insulator materials have been extensively studied in the field of condensed matter physics because nontrivial topology in the electronic state gives rise to a novel spi…
Terahertz radiation induced ballistic electron transport in graphene
Shuntaro Tani, François Blanchard, Koichiro Tanaka
We investigated ultrafast carrier dynamics in graphene with near-infrared transient absorption measurement after intense half-cycle terahertz pulse excitation. The terahertz electr…
