论文摘要
在固态物理学中，已知任何对称性断裂都与顺序参数的出现有关。然而，自发现以来，尚不清楚分子和晶体手性的顺序参数，这是奇偶校验和对称性破坏的结果。在本文中，作者表明，手性的顺序参数可以通过电动环形单极G_0来定义。根据这个定义，人们能够讨论只能通过物理领域区分两个不同的对映异构体的外部提交。另外，可以讨论阶参数G_0的动力学和波动，并可以从中获得对称为CISS的自旋滤波效果的富有成果的见解（手性诱导的自旋选择性）。讨论了G_0数量的时间传播时间传播时间的逆转偶极子M_z的出现，以解释铁磁表面上的对映选择性效果（手性分辨率）。
In solid state physics, any symmetry breaking is known to be associated with emergence of an order parameter. However, the order parameter for molecular and crystal chirality, which is a consequence of parity and mirror symmetry breaking, has not been known since its discovery. In this article, the authors show that the order parameter for chirality can be defined by electric toroidal monopole G_0. By this definition, one becomes able to discuss external filed that can distinguish two different enantiomers only by physical fields. In addition, dynamics and fluctuations of the order parameter G_0 can be discussed, with which one can obtain fruitful insights on a spin filtering effect called CISS (Chirality Induced Spin Selectivity). Emergence of time-reversal-odd dipole M_z by time propagation of G_0 quantities is discussed to explain the enantioselective effect (chiral resolution) at a ferromagnetic surface.
