Electronic Orbital Angular Momentum Driven by Finite-Momentum Phonons: Beyond Chiral and Axial Phonons
Yongho Park, Jeonghun Sohn, Sejoong Kim +1
We show that finite-momentum phonons generate electronic orbital angular momentum (OAM) even without phonon axiality or chirality, with the response controlled by the phonon wave v…

Dyakonov-Perel-like Orbital and Spin Relaxations in Centrosymmetric Systems
Jeonghun Sohn, Jongjun M. Lee, Hyun-Woo Lee
The Dyakonov-Perel (DP) mechanism of spin relaxation has long been considered irrelevant in centrosymmetric systems since it was developed originally for non-centrosymmetric ones.…
