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…

Observation of current-induced orbital quadrupole accumulation
Geun-Hee Lee, Yubin Ji, Yongho Park +12
Spintronics and orbitronics rely on current-induced accumulations of magnetic dipoles: spin and orbital angular momentum. However, electronic orbitals inherently carry multipoles b…
