Band Topology and Dynamic Multiferroicity Induced from Dynamical Dzyaloshinskii-Moriya Interactions in Centrosymmetric Lattices.

We develop a theory of a dynamical Dzyaloshinskii-Moriya interaction (dDMI) in centrosymmetric crystals by generally considering the vibration of both cations and anions. It gives rise to an antisymmetric spin-lattice coupling, inducing magnon-phonon…
