自从拓扑绝缘体被发现以来，许多拓扑相已经在一系列不同的系统中被预测和实现，为器件提供了迷人的物理学和令人兴奋的机会。尽管新材料一直在开发和探索，但如果能够在易于调整的系统中实现，探测奇异拓扑相的前景将大大增强。超冷原子提供的灵活性可以提供这样一个平台。在这里，我们回顾了光学晶格中使用超冷原子创建拓扑态的工具，概述了理论和实验进展，并展望了实现强相关拓扑相的前景。
Since the discovery of topological insulators, many topological phases have been predicted and realized in a range of different systems, providing both fascinating physics and exciting opportunities for devices. And although new materials are being developed and explored all the time, the prospects for probing exotic topological phases would be greatly enhanced if they could be realized in systems that were easily tuned. The flexibility offered by ultracold atoms could provide such a platform. Here, we review the tools available for creating topological states using ultracold atoms in optical lattices, give an overview of the theoretical and experimental advances and provide an outlook towards realizing strongly correlated topological phases.
