Large CISS Polarization from the Hierarchy Between Transport and Geometrical Spin Currents

Researchers are re-examining the chiral-induced spin selectivity (CISS) phenomenon, which shows unexpectedly large spin polarization in chiral molecular systems. They propose that a hierarchy between geometrical spin currents and transport currents explains this, suggesting that transport acts as a weak leakage from pre-existing curved spin-current states. This model could account for the high CISS polarization observed experimentally.
