论文摘要
生物呼吸道的起源是引起很多争论的主题。地球上的手性和生命的出现是对称性的突破，可以与宇宙进化中对称性的破裂进行比较。根据不对称转移的角度，分子水平的手性可能源于亚原子水平的电子自旋。因此，在本文中引入和讨论了自旋诱导的手性选择性（SICS）机制及其外展。源自量子电动力学（QED）的应力力或自旋扭矩可能是转移不对称和形成分子手性的驱动力。最近的一些实验结果似乎支持了SICS的猜想。如果自旋偏振电子（SPE）确实使生命变得更加选择性，那么一种磁性半金属材料（例如Greigite（Fe3S4））（Fe3S4）是一种矿物质，存在于原始地点的矿物质，生命可能会出现，可以用作旋转过滤器来产生SPES，然后通过SICS机械诱导非对称分子的诱导。所有这些暂定思想可能有助于解释地球早期可能出现的同虫性和生命。
The origin of bio-homochirality is a subject of much debate. The emergence of chirality and life on earth is a break of symmetry to be compared with the breaks of symmetry in the evolution of the universe. Based on a perspective of asymmetry transfer, the chirality at molecular level might stem from electron spin at subatomic level. Accordingly, in this paper a spin-induced chiral selectivity (SICS) mechanism and its outreach are introduced and discussed. The stress force or spin torque derived from quantum electrodynamics (QED) might be the driving force for the transfer of asymmetry and the formation of molecular chirality. Some recent experimental results seem to support the SICS conjecture. If spin-polarized electrons (SPEs) did cause life to become chirally selective, a magnetic half-metal material such as greigite (Fe3S4), a mineral present in a primordial site where life could have emerged, might act as a spin filter to produce SPEs, which then induced the asymmetric synthesis of chiral molecules via the SICS mechanism. All these tentative thoughts may help explain how homochirality and life could have arisen on the early Earth.
