Boundary condition for phonon distribution functions at a smooth crystal interface and interfacial angular momentum transfer
Yuta Suzuki, Shuntaro Sumita, Yusuke Kato
We theoretically elucidate the boundary conditions for phonon distribution functions of long-wavelength acoustic phonons at smooth crystal interfaces. We first derive boundary cond…
Disorder-Induced Slow Relaxation of Phonon Polarization
Yuta Suzuki, Shuichi Murakami
The role of the polarization degree of freedom in lattice dynamics in solids has been underlined recently. We theoretically discover a relaxation mechanism for both linear and circ…
Theory of phonon angular momentum transport across a smooth crystal interface
Yuta Suzuki, Shuntaro Sumita, Yusuke Kato
We theoretically elucidate the transfer of phonon angular momentum by acoustic modes across a smooth interface between crystals. We analyze this process, which is difficult to desc…
Chirality-dependent spin polarization in metals: linear and quadratic responses
Kosuke Yoshimi, Yusuke Kato, Yuta Suzuki +6
We study spin polarization induced by locally injected electric currents in a metal whose spin--orbit coupling reflects its structural chirality. We reveal both spin polarization i…
