$(3+1)$维中阿贝尔拓扑相的拓扑量子场论和环辫统计

Topological Quantum Field Theory for Abelian Topological Phases and Loop Braiding Statistics in $(3+1)$-Dimensions

摘要:

拓扑量子场论(TQFT)是研究拓扑相和相变的有力理论工具。在$2+1$ D中,众所周知,Chern-Simons理论捕获拓扑相的所有通用拓扑数据,例如,准粒子编织统计、手征中心荷甚至为我们提供了对拓扑相变本质的深刻理解。最近,量子物质的拓扑相也在$3+1$ D中得到了深入的研究,并证明了类圈激发服从所谓的三圈编织统计。本文试图建立一个TQFT框架来理解$3+1$ D中粒子和类圈激发的量子统计。为了简单起见,我们将重点放在阿贝尔拓扑相位上,然而,这里开发的一般框架并不限于阿贝尔拓扑相位。

英文摘要:

Topological qauntum field theory(TQFT) is a very powerful theoretical tool to study topological phases and phase transitions. In $2+1$D, it is well known that the Chern-Simons theory captures all the universal topological data of topological phases, e.g., quasi-particle braiding statistics, chiral central charge and even provides us a deep insight for the nature of topological phase transitions. Recently, topological phases of quantum matter are also intensively studied in $3+1$D and it has been shown that loop like excitation obeys the so-called three-loop-braiding statistics. In this paper, we will try to establish a TQFT framework to understand the quantum statistics of particle and loop like excitation in $3+1$D. We will focus on Abelian topological phases for simplicity, however, the general framework developed here is not limited to Abelian topological phases.
