Observation of Terahertz Spin Hall Conductivity Spectrum in GaAs with Optical Spin Injection
Tomohiro Fujimoto, Takayuki Kurihara, Yuta Murotani +7
We report the first observation of the spin Hall conductivity spectrum in GaAs at room temperature. Our terahertz polarimetry with a precision of several rads resolves the Farad…

Disentangling the Competing Mechanisms of Light-Induced Anomalous Hall Conductivity in Three-Dimensional Dirac Semimetal
Yuta Murotani, Natsuki Kanda, Tomohiro Fujimoto +7
We experimentally elucidate the origin of the anomalous Hall conductivity in a three-dimensional Dirac semimetal, CdAs, driven by circularly polarized light. Using time-res…
