  To realize Majorana fermions having novel physical features has been
developed as a key while difficult task in topological superconductor. Here we
have proposed another platform to generate Majorana zero modes (MZMs), which is
constructed by a single opened circular helix molecules (CHM) coupled with a
s-wave superconductor (with magnetic field) or by an interlinked-CHMs chain
coupled with a phase-bias s-wave superconducting heterostructure (without any
magnetic field). The MZMs achieved here are tightly associated with the
structural chirality in CHMs. Importantly, the left and right handedness may
result in completely opposite Majorana polarization (MP), and the local MP is
associated to the chiraliy-induced spin polarization. These properties provides
us multiple effective ways to detect and regulate the MZMs by using the
chirality-induced spin selectivity (CISS) effect and the related spin-polarized
currents in chiral materials.
