The recent development of artificially fabricated van der Waals nanostructures makes it possible to design and control the symmetry of solids and to find novel physical properties and related functionalities. A characteristic physical property reflecting such symmetry breaking is the nonlinear response, which is typically studied as the second harmonic generation of light, although studies have recently expanded to include various transport phenomena. An important aspect of nonlinear transport for modern condensed matter physics is that it is not only a unique functionality of noncentrosymmetric systems but also an emergent property reflecting underlying physics such as spin–orbit interaction, superconductivity, magnetism, and band geometry/topology.

范德华纳米结构中的对称破坏和非线性电输运

人造范德华纳米结构的最新发展使设计和控制固体的对称性以及发现新颖的物理性质和相关功能成为可能。反映这种对称性破坏的特征物理特性是非线性响应,尽管最近研究已经扩展到包括各种传输现象,但非线性响应通常被研究为光的二次谐波。非线性传输对于现代凝聚态物理的一个重要方面是,它不仅是非中心对称系统的独特功能,而且是反映基础物理的新兴属性,例如自旋-轨道相互作用,超导性,磁性和能带几何/拓扑。
