Phonon Edelstein effect in chiral metals
Takehito Yokoyama
We propose a mechanism of current-induced phonon angular momentum, which we call phonon Edelstein effect. We investigate this effect in three-dimensional chiral metals with spin-or…
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…
Spin-spin interaction mediated by chiral phonons
Takehito Yokoyama
We study interaction between two magnetic impurities on top of a two dimensional insulator in the presence of chiral phonons by second-order perturbation theory. We show that this…
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…
