Chirality-Induced\nMajorana Zero Modes and Majorana\nPolarization

Realizing Majorana Fermions has always been regarded\nas a crucial\nand formidable task in topological superconductors. In this work,\nwe report a physical mechanism and a material platform for realizing\nMajorana zero modes (MZMs). This material platform consists of open\ncircular helix molecule (CHM) proximity coupled with an <i>s</i>-wave superconductor (under an external magnetic field) or interconnected-CHM\nchain coupled with a phase-bias <i>s</i>-wave superconducting\nheterostructure (without any external magnetic field). MZMs generated\nhere are tightly associated with the structural chirality in CHMs.\nNotably, the left- and right-handedness results in completely opposite\nMajorana polarization (MP), leading us to refer to this phenomenon\nas chirality-induced MP (CIMP). Importantly, the local CIMP is closely\nlinked to chirality-induced spin polarization, providing us with an\neffective way to regulate MZMs through the chirality-induced spin\nselectivity (CISS) effect. Furthermore, MZMs can be detected by the\nspin-polarized current measurements related to the CISS in chiral\nmaterials.
