论文摘要
拓扑是数学中建立的一个概念，如今已成为描述凝结物问题的必不可少的。其核心是凝结物质系统的整体，表面和边缘上的手性电子状态，其中电子的自旋和动量彼此平行或平行。例如，磁性和非磁性Weyl半学表现出手性散装状态，这些状态能够实现涉及手性量子数的高能量和天体物理学的预测，例如手性异常，混合的轴向雷神异常异常和轴。将手性作为量子数与其他科学领域的其他手性现象联系起来的潜力，包括物质和反物质的不对称性以及生命的同质性，将拓扑材料带到了前面。
Topology, a well-established concept in mathematics, has nowadays become essential to describe condensed matter. At its core are chiral electron states on the bulk, surfaces and edges of the condensed matter systems, in which spin and momentum of the electrons are locked parallel or anti-parallel to each other. Magnetic and non-magnetic Weyl semimetals, for example, exhibit chiral bulk states that have enabled the realization of predictions from high energy and astrophysics involving the chiral quantum number, such as the chiral anomaly, the mixed axial-gravitational anomaly and axions. The potential for connecting chirality as a quantum number to other chiral phenomena across different areas of science, including the asymmetry of matter and antimatter and the homochirality of life, brings topological materials to the fore.
