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…
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…
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…
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…
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…
