准晶中的拓扑
Topology in quasicrystals
摘要:
近几十年来,物质的拓扑相引发了大量的活动。拓扑材料的分类拓扑不变量,作为一个非本地的序参量的任何对称性和条件。因此,它们表现出量化的体积和边界可观察的现象,激励各种应用程序,是强大的扰动。在这篇综述中,我们探讨了这样的准周期系统的拓扑分类,并详细介绍了该领域最近的实验活动。
英文摘要:
Topological phases of matter have sparked an immense amount of activity in recent decades. Topological materials are classified by topological invariants that act as a non-local order parameter for any symmetry and condition. As a result, they exhibit quantized bulk and boundary observable phenomena, motivating various applications that are robust to perturbations. In this review, we explore such a topological classification for quasiperiodic systems, and detail recent experimental activity in the field.
