Nonlocality of electrically-induced spin accumulation in chiral metals

Abstract
Spin accumulation induced by an electric field in chiral electron system is investigated based on a linear response theory. It is shown that the spin response function has a spatially uniform component due to the chiral angular momentum generation effect, resulting in a nonlocal spin generation. The result suggests a scenario for nonlocal long-range spin transport in chiral metals reported experimentally recently.
