Abstract
Despite extensive experiments, chiral-induced spin selectivity (CISS) remains debated. Using a donor-double-stranded DNA-acceptor model and Lindblad equation, we define spin mobility polarization via spin-resolved mean-square displacement and fix relaxation on a turnover plateau. Spin-independent relaxation locks the transient asymmetry from helical spin-orbit coupling (SOC) into a steady polarization. Weak SOC, expected to have little effect, boosts one spin but suppresses the other instead, in a "one enhanced, one suppressed" pattern. Flipping the helix exchanges them. The work defines mobility polarization as a probe and gives a generic dissipation-driven mechanism for CISS.
