Abstract

This research uses density functional theory (DFT) + PAOFLOW calculations to quantitatively estimate the collinear Rashba-Edelstein effect (REE) in chiral crystals, revealing that spin accumulation induced by an electric current is protected by the quasi-persistent spin helix. This long-range spin transport, unlike conventional REE, opens avenues for solid-state spintronics devices.
