Chirality-Selective Phonon Pumping by Ferroelectric Dynamics
Dapeng Yao, Ping Tang
The discovery of chiral phonons has expanded the conventional view of lattice vibrations as passive heat carriers, opening new opportunities for phononic spintronic devices. Howeve…
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…
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…
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…
Electric field-induced nonreciprocal spin current due to chiral phonons in chiral-structure superconductors
Dapeng Yao, Mamoru Matsuo, Takehito Yokoyama
The recent experiment [R. Nakajima, et al., Nature 613, 479 (2023)] has reported a pair of oppositely polarized spins under an alternating electric current in a superconductor with…
