Emergence of Chiral Helimagnetic Order in Chromium-intercalated Tantalum Disulfide CrTaS Powders with Controlled Intercalation
Ayaka Toshima, Keigo Mizutani, Yusuke Kousaka +3
We report a highly sensitive change in magnetic properties of a chiral Cr-intercalated transition-metal dichalcogenide CrTaS. Magnetization curves and small-angle…
Temperature dependence of charge-to-spin conversion in rhombohedral (110) bismuth thin film
K. Tatsuoka, N. Fukumoto, S. Sakamoto +7
The amplitude of charge-to-spin conversion, namely the spin Hall effect (SHE), in bismuth (Bi) strongly depends on its crystal orientation. The conversion efficiency at room temper…
Degenerate Soft Modes and Selective Condensation in BaAlO via Inelastic X-ray Scattering
Yui Ishii, Arisa Yamamoto, Alfred Q. R. Baron +2
BaAlO is a ferroelectric material that exhibits structural quantum criticality through chemical composition tuning. Although theoretical calculations and several diffractio…
Impact of in-plane disorders on the thermal conductivity of AgCrSe
Shota Izumi, Yui Ishii, Jinfeng Zhu +5
Superionic conductors have recently attracted renewed attention for their use as thermoelectric materials due to their extremely low lattice thermal conductivity. Of central intere…
Electron-Chiral Phonon Coupling, Crystal Angular Momentum, and Phonon Chirality
Tomomi Tateishi, Akihito Kato, Jun-ichiro Kishine
We explicitly derive the wavefunctions of chiral phonons propagating along the helical axis in chiral crystals and clarify the characteristics of electron-phonon interactions in ch…
Description of molecular chirality and its analysis with high harmonic generation
Akihito Kato, Nobuhiko Yokoshi
To clarify the microscopic origin of chirality-induced optical effect, we develop an analytical method that extracts the chiral part of the Hamiltonian of molecular electronic stat…
