AI 中文摘要
手性诱导自旋选择性(CISS)效应,即结构手性与电子自旋极化之间的耦合,已在多种不同系统中被实验观测到。然而,尽管进行了大量的理论努力,统一的机理解释仍然难以捉摸。在这篇展望中,我们展示了如何基于基本粒子物理学中常用的直接对称性考量来理解CISS这一引人入胜效应的某些基本性质。特别是,我们表明CISS不违反任何基本对称性,包括宇称和时间反演。通过将CISS锚定在对称性的通用语言中,我们为解释实验和指导未来的理论与实验设计提供了稳健的概念基础。
英文摘要
The chirality-induced spin selectivity (CISS) effect, the coupling between structural chirality and electron spin polarization, has been experimentally observed across many diverse systems. However, despite extensive theoretical effort, a unified mechanistic understanding remains elusive. In this perspective, we demonstrate how some of the basic properties of the fascinating effects of CISS can be understood based on straightforward symmetry considerations commonly employed in fundamental particle physics. In particular, we show that CISS does not violate any fundamental symmetries including parity and time-reversal. By anchoring CISS within the universal language of symmetry, we offer a robust conceptual foundation for interpreting experiments and guiding future theoretical and experimental designs.
