Intrinsic orbital Hall effect in a nonuniform electric field
Min Ju Park, Jongjun M. Lee, Hyun-Woo Lee
Geometric analysis of electronic Bloch states offers a universal framework for understanding electronic properties, yet its role in the transport of orbital angular momentum remain…
Orbital Pumping Incorporating Both Orbital Angular Momentum and Position
Seungyun Han, Hye-Won Ko, Jung Hyun Oh +3
We develop a theory of adiabatic orbital pumping, highlighting qualitative differences from spin pumping. An oscillating magnetic field pumps not only orbital angular momentum curr…
Orbital Edelstein effect of electronic itinerant orbital motion at edges
Jongjun M. Lee, Min Ju Park, Hyun-Woo Lee
In the study of orbital angular momentum (OAM), the focus has been predominantly on the intra-atomic contribution. However, recent research has begun to shift towards exploring the…
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.…
Nonlinear Orbital and Spin Edelstein Effect in Centrosymmetric Metals
Insu Baek, Seungyun Han, Suik Cheon +1
Nonlinear spintronics combines nonlinear dynamics with spintronics, opening up new possibilities beyond linear responses. A recent theoretical work [Xiao et al., Phys. Rev. Lett. 1…
