分形拓扑序、广义格点规范理论和对偶

Fracton Topological Order, Generalized Lattice Gauge Theory and Duality

Sagar Vijay, Jeongwan Haah, Liang Fu

摘要:

我们介绍了一个推广的传统格点规范理论来描述分形拓扑相位,其特征在于固定的,点状的拓扑激发,和次广泛的拓扑简并。我们证明了分形拓扑秩序和相互作用的自旋系统的对称性沿广泛的,低维的子系统,这可能是用来系统地搜索和表征分形拓扑相位之间的对偶性。交换代数和初等代数几何为我们的结果提供了一个有效的数学工具。我们的工作铺平了道路,确定可能的材料实现分形拓扑相位。

英文摘要:

We introduce a generalization of conventional lattice gauge theory to describe fracton topological phases, which are characterized by immobile, point-like topological excitations, and sub-extensive topological degeneracy. We demonstrate a duality between fracton topological order and interacting spin systems with symmetries along extensive, lower-dimensional subsystems, which may be used to systematically search for and characterize fracton topological phases. Commutative algebra and elementary algebraic geometry provide an effective mathematical toolset for our results. Our work paves the way for identifying possible material realizations of fracton topological phases.
