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…
Anti-Stokes Photoluminescence from CsPbBr3 Nanostructures Embedded in a CsPbBr Crystal
Yuto Kajino, Shuji Otake, Takumi Yamada +6
Lead halide perovskites possess high photoluminescence (PL) efficiency and strong electron-phonon interactions, and therefore the optical cooling using up-conversion PL has been ex…
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…
Polaron Masses in CH3NH3PbX3 Perovskites Determined by Landau Level Spectroscopy in Low Magnetic Fields
Yasuhiro Yamada, Hirofumi Mino, Takuya Kawahara +3
We investigate the electron-phonon coupling in CH3NH3PbX3 lead halide perovskites through the observation of Landau levels and high-order excitons at weak magnetic fields, where th…
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…
Observation of charged excitons in hole-doped carbon nanotubes using photoluminescence and absorption spectroscopy
Ryusuke Matsunaga, Kazunari Matsuda, Yoshihiko Kanemitsu
We report the first observation of trions (charged excitons), three-particle bound states consisting of one electron and two holes, in hole-doped carbon nanotubes at room temperatu…
Femtosecond Excitation Correlation Spectroscopy of Single-Walled Carbon Nanotubes : Analysis Based on Nonradiative Multiexciton Recombination Processes
Yuhei Miyauchi, Kazunari Matsuda, Yoshihiko Kanemitsu
We studied the nonlinear time-resolved luminescence signals due to multiexciton recombination processes in single-walled carbon nanotubes (SWNTs) using femtosecond excitation corre…
Intersubband electronic Raman scattering in narrow GaAs single quantum wells dominated by single-particle excitations
Takeya Unuma, Kensuke Kobayashi, Aishi Yamamoto +6
We measured resonant Raman scattering by intersubband electronic excitations in GaAs/AlAs single quantum wells (QWs) with well widths ranging from 8.5 to 18 nm. In narrow (less tha…
