Query: Magnetochiral Polarization and High Order Transport in DNA type Chiral
  Materials   The chirality--spin interaction is a fascinating topic for both physicists
and chemists. For example, chiral molecules like DNA generate giant spin
polarization in nanodevices characterized by large magnetoresistance. This
phenomenon called chiral induced spin selectivity (CISS) in literature, paves
pathways for unconventional spintronic devices and enantiomer separation.
However, its physical mechanism is elusive and debated. In this work, we find
that the CISS magnetoresistance is a high-order effect and originates from the
current-driven charge accumulation at metal-chiral molecule interfaces.
Reversing lead magnetization modulates the charge polarization and consequently
changes the tunneling barrier across the molecule. The magnetoresistance
increases with the barrier width and bias and can theoretically approach 100\%.
This mechanism can be validated by examining the insulation of chiral
molecules, spin-orbit coupling in leads, or frequency-dependence of surface
potential. Further, we propose that emerging twisted van der Waals quantum
materials will be a versatile platform for CISS and similar spin selective
phenomena.
