论文摘要
拓扑绝缘子和半法的发现开辟了一种新的观点，可以理解材料。由于特殊的带结构和扩大的浆果曲率，拓扑材料的线性响应得到了强烈增强。拓扑带结构和对称性的相互作用对于设计具有强烈和异国情调的新电磁响应的新材料起着至关重要的作用，并为下一代技术应用提供了有希望的机制和新材料。我们从对称的角度回顾了拓扑材料中线性响应的基本概念，并讨论了它们的潜在应用。
The discovery of topological insulators and semimetals has opened up a new perspective to understand materials. Owing to the special band structure and enlarged Berry curvature, the linear responses are strongly enhanced in topological materials. The interplay of topological band structure and symmetries plays a crucial role for designing new materials with strong and exotic new electromagnetic responses and provides promising mechanisms and new materials for the next generation of technological applications. We review the fundamental concept of linear responses in topological materials from the symmetry point of view and discuss their potential applications.
