摘要

d维量子场论（QFT）的对称数据通常可以用高维对称拓扑场论来捕获。在这种结构的自顶向下（即，弦）实现中，所讨论的QFT被定位在高维体中。然而，在许多感兴趣的情况下，相关的（d+1）维体积不是完全间隙的，因此必须考虑过滤理论以达到d =d+m维的间隙体积。总的来说，这导致我们得到一个相对对称理论的嵌套结构，它下降到耦合的边缘模式，原始的QFT自由度定位在这个d维体系统的一个角落。我们提出了这种结构的自下而上的表征，并展示了它如何自然地出现在具有有限对称性和连续对称性的基于字符串的qft结构中。2025年由美国物理学会出版

Cornering relative symmetry theories

The symmetry data of a d-dimensional quantum field theory (QFT) can often be captured in terms of a higher-dimensional symmetry topological field theory. In top-down (i.e., stringy) realizations of this structure, the QFT in question is localized in a higher-dimensional bulk. In many cases of interest, however, the associated (d+1)-dimensional bulk is not fully gapped and one must instead consider a filtration of theories to reach a gapped bulk in D=d+m dimensions. Overall, this leads us to a nested structure of relative symmetry theories which descend to coupled edge modes, with the original QFT degrees of freedom localized at a corner of this D-dimensional bulk system. We present a bottom-up characterization of this structure and also show how it naturally arises in a number of string-based constructions of QFTs with both finite and continuous symmetries.
