Abstract

The topological phase of matter, originally proposed and first demonstrated in fermionic electronic systems, has drawn considerable research attention in the past decades due to its robust transport of edge states and its potential with respect to future quantum information, communication, and computation. Recently, searching for such a unique material phase in bosonic systems has become a hot research topic worldwide. So far, many bosonic topological models and methods for realizing them have been discovered in photonic systems, acoustic systems, mechanical systems, etc. These discoveries have certainly yielded vast opportunities in designing material phases and related properties in the topological domain. In this review, we first focus on some of the representative photonic topological models and employ the underlying Dirac model to analyze the edge states and geometric phase. On the basis of these models, three common types of two-dimensional topological photonic systems are discussed: 1) photonic quantum Hall effect with broken time-reversal symmetry; 2) photonic topological insulator and the associated pseudo-time-reversal symmetry-protected mechanism; 3) time/space periodically modulated photonic Floquet topological insulator. Finally, we provide a summary and extension of this emerging field, including a brief introduction to the Weyl point in three-dimensional systems.

二维拓扑光子系统
物质的拓扑相位最初是在费米电子系统中提出并首次证明的,由于其边缘态的鲁棒输运及其在未来量子信息、通信和计算方面的潜力,在过去几十年中引起了相当大的研究关注。近年来,在玻色子系统中寻找这样一种独特的物质相已成为世界范围内的研究热点。迄今为止,在光子系统、声学系统、机械系统等领域已经发现了许多玻色子拓扑模型及其实现方法。这些发现无疑为设计拓扑领域的材料相和相关性质提供了巨大的机会。在这篇综述中,我们首先关注了一些有代表性的光子拓扑模型,并利用底层的狄拉克模型分析了边缘态和几何相位。在这些模型的基础上,讨论了三种常见的二维拓扑光子系统:1)具有破缺时间反转对称性的光子量子霍尔效应;2)光子拓扑绝缘子及其伪时间反转对称保护机制;3)时间/空间周期调制光子Floquet拓扑绝缘子。最后,我们对这一新兴领域进行了总结和扩展,包括对三维系统中的Weyl点的简要介绍。
