Symmetry constraints on the orbital transport in solids
arXiv:2309.04442 · doi:10.1103/PhysRevB.108.L180404
Abstract
We show that electron interaction with the crystal lattice imposes stringent symmetry constrains on the orbital moment propagation. We present examples that elucidate the underlying mechanisms and reveal an additional effect of ultrafast orbital moment oscillations not captured by the semiclassical models. The constraints revealed by our analysis warrant re-interpretation of prior observations, and suggest routes for efficient orbitronic device implementation.
One of the main findings is that the orbital current generated by orbital Hall effect is not a well-defined physical quantity
