First Direct Observation of the Angular Momentum of Chiral Phonons

Topic:

Scientific Achievement: Cantilever-based measurement demonstrated that collective chiral atomic vibrations, known as chiral phonons, possess and transport angular momentum, connecting quantum properties to mechanical responses.

Significance and Impact: Provides evidence of phonon angular momentum, a basis for lattice control of quantum phenomena with potential applications in microelectronics.
