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…

Superconductivity in Ternary Germanite TaAl $_{x}$ Ge $_{2 - x}$ with a C40 chiral structure

Daigo Koizumi, Shingo Kisanuki, Kenta Monden +3

We report a new family of chiral intermetallic superconductors TaAl $_{x}$ Ge $_{2 - x}$ . The mother compound TaGe $_{2}$ has a C40-type chiral hexagonal crystal structure with a pair of e…
