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.
