耦合线非阿贝尔拓扑相的基态简并性

Ground state degeneracy of non-Abelian topological phases from coupled wires

Thomas Iadecola, Titus Neupert, Claudio Chamon, Christopher Mudry

摘要:

我们构造了一个家庭的二维非阿贝尔拓扑相位耦合线使用非阿贝尔玻色化方法。然后,我们演示了如何确定的非阿贝尔拓扑顺序(特别是,任何电子激发和拓扑退化的环面)实现在所产生的有间隙的阶段的物质的性质。本文着重于玻色子$su(2)^{\,}_{2}$ Moore-Read态的耦合线实现的详细案例研究,但我们在这里概述的方法可以扩展到一般的玻色子$su(2)^{\,}_{k}$拓扑相描述的非阿贝尔陈-西蒙斯理论。我们还讨论了可能的推广这种方法的建设三维非阿贝尔拓扑相位。

英文摘要:

We construct a family of two-dimensional non-Abelian topological phases from coupled wires using a non-Abelian bosonization approach. We then demonstrate how to determine the nature of the non-Abelian topological order (in particular, the anyonic excitations and the topological degeneracy on the torus) realized in the resulting gapped phases of matter. This paper focuses on the detailed case study of a coupled-wire realization of the bosonic $su(2)^{\,}_{2}$ Moore-Read state, but the approach we outline here can be extended to general bosonic $su(2)^{\,}_{k}$ topological phases described by non-Abelian Chern-Simons theories. We also discuss possible generalizations of this approach to the construction of three-dimensional non-Abelian topological phases.
