Webchiral phonons were experimentally verified in mono-layer WSe 2 [11]. The finding of phonon chirality is a significant progress since it reveals that phonon, a kind of Bosonic … WebFurther, Ref. [15] suggested that the chiral phonon can induce inertial e ects on the electrons, which lead to an e ective spin-chiral phonon coupling. Therefore, elec-tronic contributions to the phonon magnetic moment open the possibility for the interplay of chiral phonons and electronic topology [14]. However, no experimental
