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…
Size-controlled quantum dots reveal the impact of intraband transitions on high-order harmonic generation in solids
Kotaro Nakagawa, Hideki Hirori, Shunsuke A. Sato +7
Since the discovery of high-order harmonic generation (HHG) in solids, much effort has been devoted to understanding its generation mechanism and both interband and intraband trans…
High-order harmonic generation in graphene: nonlinear coupling of intra and interband transitions
Shunsuke A. Sato, Hideki Hirori, Yasuyuki Sanari +2
We investigate high-order harmonic generation (HHG) in graphene with a quantum master equation approach. The simulations reproduce the observed enhancement in HHG in graphene under…
Zener Tunneling Breakdown in Phase-Change Materials Revealed by Intense Terahertz Pulses
Yasuyuki Sanari, Takehiro Tachizaki, Yuta Saito +8
We have systematically investigated the spatial and temporal dynamics of crystallization that occurs in the phase-change material Ge2Sb2Te5 upon irradiation with an intense THz pul…
Resonant Spin Wave Excitation by Terahertz Magnetic Near-field Enhanced with Split Ring Resonator
Y. Mukai, H. Hirori, T. Yamamoto +2
Excitation of antiferromagnetic spin waves in HoFeO crystal combined with a split ring resonator (SRR) is studied using terahertz (THz) electromagnetic pulses. The magnetic f…
Single-cycle THz pulses with amplitudes exceeding 1 MV/cm generated by optical rectification in LiNbO3
H. Hirori, A. Doi, F. Blanchard +1
Using the tilted-pulse-intensity-front scheme, we generate single-cycle terahertz (THz) pulses by optical rectification of femtosecond laser pulses in LiNbO3. In the THz generation…
Real-time terahertz near-field microscope
F. Blanchard, A. Doi, T. Tanaka +4
Terahertz (THz) waves have been significantly developed in the last fifteen years because of their great potential for applications in industrial and scientific communities1,2. The…
