Dynamical Orbital Angular Momentum Induced by Circularly Polarized Phonons
Dapeng Yao, Dongwook Go, Yuriy Mokrousov +1
We show that the orbital angular momentum (OAM) of electrons is dynamically induced by circularly polarized phonons. The induced OAM originates from the adiabatic evolution in whic…
Magnetism and Topology from Circularly Polarized Phonon Floquet Engineering
Dapeng Yao, Tiantian Zhang, Takashi Oka +1
We theoretically show that circularly polarized phonons induce electronic magnetization and drive a topological phase transition via phonon Floquet engineering. Considering the ele…
Theory of spin magnetization driven by chiral phonons
Dapeng Yao, Shuichi Murakami
We construct a general theory of spin magnetization driven by chiral phonons under an adiabatic process, in which atoms rotate around their equilibrium positions with a low phonon…
Chiral magnon in ferromagnetic chiral crystals
Dapeng Yao, Takehito Yokoyama
We theoretically propose chiral magnon in ferromagnetic chiral crystals. We show that the crystal chirality is imprinted in orbital angular momentum of magnons which exhibits the o…
