Acoustic Rashba–Edelstein effect

We theoretically study the mechanical induction of spin density via Rashba spin--orbit interaction (SOI). The in linear response to lattice distortion dynamics is calculated based on microscopic theory. reveal that there are two mechanisms induction: one acoustic Edelstein effect (AEE) from acceleration and other caused by spin--vorticity coupling (RSVC). find AEE induces a more efficient spin-to-charge conversion comparison with conventional electric effect. induced due RSVC expressed as Berry curvature-like quantity; therefore, it can be attributed spatial symmetry breaking SOI. Our work demonstrates high-efficiency generation systems.
