Chirality-Induced Spin Selectivity: Nonlinear Spin Response from Electron-Phonon Scattering
First-principles density-matrix simulations distinguish CISS from the linear Edelstein effect by showing that spin-dependent electron-phonon scattering yields S_z proportional to E squared plus length-dependent accumulation via intervalley chiral-phonon processes.
