Chirality-Induced Selectivity of Phonon Angular Momenta in Chiral Quartz Crystals
Kazuki Ohe, Hiroaki Shishido, Masaki Kato +3
A generation, propagation, and transfer of phonon angular momenta are examined on thermal transport in chiral insulative and diamagnetic crystals of -quartz. We found that ther…
