Extrinsic Mechanisms of Phonon Magnetic Moment

Author(s): Rui Xue, Zhenhua Qiao, Yang Gao, and Qian Niu We develop a general formalism of the phonon magnetic moment by including the relaxation processes. We then identify the skew-scattering and side-jump contributions to the phonon magnetic moment originating from the nonadiabaticity, both of which are related to the nonlocal phonon Berry curvature an… [Phys.
