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…
