论文摘要
我们描述了从耦合的下维对称性拓扑秩序耦合的拓扑顺序的结构，这与测量子系统对称性密切相关。我们的构建产生了常规的拓扑命令，以及I型和II型的异国情调的拓扑拓扑顺序。特别是，我们发现了HAAH的立方密码的耦合自旋链结构，以及吉田分形旋转液体的耦合层结构。
We describe a construction of topological orders from coupled lower dimensional symmetry-protected topological orders, which is closely related to gauging a subsystem symmetry. Our construction yields both conventional topological orders and exotic fracton topological orders of type-I and type-II. In particular, we find a coupled spin chain construction of Haah's cubic code, and a coupled layer construction of Yoshida's fractal spin liquids.
