Circular Raman responses from angular-momentum inequivalence in CoSi
Yuki Suganuma, Gakuto Kusuno, Kohei Miyazaki +8
Circularly polarized Raman scattering in solids exhibits distinct phenomena such as Raman optical activity (ROA) and chiral-phonon-induced frequency splitting, whose relationship h…
Quantifying chirality of phonons
Yu-Chi Huang, Gakuto Kusuno, Yusuke Hashimoto +3
Recent years have witnessed growing interest in chiral phonons, lattice vibrations carrying angular momentum and exhibiting handedness, as revealed by helicity-dependent optical ph…
Electric toroidal octupolar symmetry in pyrite FeS probed by Raman optical activity
Yuki Suganuma, Gakuto Kusuno, Hikaru Watanabe +4
We report Raman optical activity in pyrite FeS, which hosts an electric toroidal octupolar symmetry. A clear and reproducible sign reversal of the circular intensity difference…
Symmetry analysis of cross-circular and parallel-circular Raman optical activity
Hikaru Watanabe, Rikuto Oiwa, Gakuto Kusuno +2
The Raman scattering regarding the circularly-polarized incident and scattered lights is closely related to the circular activity of a given system. We investigate the symmetry of…
Raman Optical Activity Induced by Ferroaxial Order in NiTiO
Gakuto Kusuno, Takeshi Hayashida, Takayuki Nagai +4
Raman optical activity (ROA), the dependence of Raman intensity on the circular polarization of incident and scattered light, has traditionally been observed in chiral molecules an…
Polarization-dependent photocurrent in a quadrilateral-shaped bulk crystalline tellurium chip with near-infrared light excitation
Hiro Munekata, Gakuto Kusuno, Kohei Miyazaki +1
We report the detection of zero-bias photocurrents induced by interband excitation using oblique near-infrared light (λ=0.780 μm) along the directions parallel and perpendicular to…
