AI中文摘要:
我们研究了(2+1)维拓扑量子场论(TQFT)的可逆一形式全局对称性。该对称性的一个普适描述将所有的阿贝尔任意子从TQFT的其余部分“剥离”出来。这使得我们能够独立于系统其余部分的细节来研究该对称性及其一些后果。然后,我们使用带有陈-西蒙斯项的U(1)规范场来描述这些阿贝尔任意子,并将它们耦合到一个标量场,从而构建了一个特定的非拓扑理论。这个新理论,即我们的跃迁场论,表现出从原始TQFT到另一个相的相变。后者要么是无能隙的,要么是另一个TQFT。这一讨论推广并扩展了我们之前的工作(arXiv:2603.00245)。特别是,我们更详细地描述了全局对称性及其在各个相中的命运。
英文摘要:
We study the invertible one-form global symmetry of a (2+1)-dimensional topological quantum field theory (TQFT). A universal description of this symmetry ``peels off'' all the Abelian anyons from the rest of the TQFT. This allows us to study this symmetry and some of its consequences, independently of the details of the rest of the system. We then describe these Abelian anyons using $\mathrm{U}(1)$ gauge fields with Chern-Simons terms and couple them to a scalar field, thus constructing a particular non-topological theory. This new theory, our transition field theory, exhibits a phase transition from the original TQFT to another phase. The latter is either gapless or another TQFT. This discussion generalizes and extends our earlier work (arXiv:2603.00245). In particular, we give a more detailed description of the global symmetries and their fates in the various phases.
