Time- and Frequency-Resolved Observation of Inverse Orbital Hall Effect in Gallium Nitride via Terahertz Polarimetry
Kota Aikyo, Tomohiro Fujimoto, Ami Mi Shirai +6
Orbitronics has attracted significant attention as a platform for information storage and processing that exploits the orbital angular momentum (OAM) of electrons without the need…
Calculations in Unified theory of the photovoltaic Hall effect by field- and light-induced Berry curvatures
Yuta Murotani, Tomohiro Fujimoto, Ryusuke Matsunaga
Photovoltaic Hall effect is an interesting platform of Berry curvature engineering by external fields. Floquet engineering aims at generation of light-induced Berry curvature assoc…
Unified theory of the photovoltaic Hall effect by field- and light-induced Berry curvatures
Yuta Murotani, Tomohiro Fujimoto, Ryusuke Matsunaga
Photovoltaic Hall effect, i.e., generation of a photocurrent perpendicular to the bias electric field, is an interesting platform of Berry curvature engineering by external fields.…
Valley polarization dynamics of photoinjected carriers at the band edge in room-temperature silicon studied by terahertz polarimetry
Ami M. Shirai, Yuta Murotani, Tomohiro Fujimoto +3
Sixfold-degenerate valleys in Si have attracted considerable attention for valleytronics application. Using optical pump-terahertz (THz) probe spectroscopy, we study the dynamics o…
Light-induced inverse spin Hall effect and field-induced circular photogalvanic effect in GaAs revealed by two-dimensional terahertz Fourier analysis
Tomohiro Fujimoto, Yuta Murotani, Tomohiro Tamaya +7
The electromotive force transverse to a bias field under irradiation of circularly polarized light, namely the photovoltaic Hall response or light-induced anomalous Hall effect, ha…
