Abstract: Recently, phonons with chirality (chiral phonons) have attracted significant attention. Chiral phonons exhibit angular and pseudoangular momenta. In circularly polarized Raman spectroscopy, the peak split of the Γ 3 $$ {\Gamma}_3 $$ mode is detectable… read more here.

Abstract: Chiral phonons have recently been established to emerge in systems containing intrinsically chiral atomic structures or magnetic systems. Here we show that such intriguing chiral phonons can also be induced in nonmagnetic Kagome lattices that… read more here.

DOI: 10.1103/physrevb.104.054103

Abstract: As a potential degree of freedom, the chirality of phonons is expected to become a carrier of information. Exploring the phonon mode that can stably maintain chirality along a certain transport path is the basis… read more here.

DOI: 10.1126/sciadv.abm4005

Abstract: Chiral symmetry breaking of phonons plays an essential role in emergent quantum phenomena owing to its strong coupling to spin degree of freedom. However, direct experimental evidence of the chiral phonon–spin coupling is lacking. In… read more here.
