Chiral phonons and pseudoangular momentum in nonsymmorphic systems
Chiral phonons have nonzero polarization and can be observed only via a selective coupling with valley electrons and circularly polarized photons. In such process, a new physical quantity, i.e., pseudoangular momentum (PAM), is required to meet the selection rule. However, phonon PAM was only studie...
