Topological nanophotonics is a new avenue for exploring nanoscale systems from visible to THz frequencies, with unprecedented control. By embracing their complexity and fully utilizing the properties that make them distinct from electronic systems, we aim to study new topological phenomena. In this Perspective, we summarize the current state of the field and highlight the use of nanoparticle systems for exploring topological phases beyond electronic analogues. We provide an overview of the tools needed to capture the radiative, retardative, and long-range properties of these systems. We discuss the application of dielectric and metallic nanoparticles in nonlinear systems and also provide an overview of the newly developed topic of topological insulator nanoparticles. We hope that a comprehensive understanding of topological nanoparticle photonic systems will allow us to exploit them to their full potential and explore new topological phenomena at very reduced dimensions.
拓扑纳米光子学是探索从可见光到太赫兹频率的纳米级系统的一条新途径，具有前所未有的控制能力。通过接受其复杂性并充分利用使其有别于电子系统的特性，我们旨在研究新的拓扑现象。在这篇展望文章中，我们总结了该领域的当前状态，并强调了使用纳米粒子系统来探索超越电子类似物的拓扑相。我们概述了捕捉这些系统的辐射、延迟和长程特性所需的工具。我们讨论了介电和金属纳米粒子在非线性系统中的应用，还概述了拓扑绝缘体纳米粒子这一新兴主题。我们希望对拓扑纳米粒子光子系统的全面理解将使我们能够充分发挥其潜力，并在非常小的尺寸下探索新的拓扑现象。
