Chiral phonons in sixfold chiral CrSi${}_2$: Raman spectroscopy and first-principles calculations

Gakuto Kusuno, Shingo Kisanuki, Yusuke Kousaka +2

Chiral phonons have been identified in several chiral crystals, primarily in those with trigonal symmetry and threefold screw axes. In this study, chiral phonons in CrSi${}_2$, a chi…
