AI 中文摘要
近期一项研究表明，对量子场论的对称性进行迭代规范可产生一个涌现的额外空间维度。本文明确了这一现象背后的精确机制：它是维度解构，即通过箭图规范理论的结构编码额外维度的过程。我们通过证明标准解构作用量在希格斯分支上对偶化戈德斯通场后，与迭代规范产生的作用量完全等价来展示这一点。对应关系清晰：箭图节点对应规范场，箭图连线对应为耦合磁对称性引入的规范场。我们进一步证明，从规范电对称性而非磁对称性开始，会得到用对偶变量书写的解构理论，且所有耦合常数均取倒数。
英文摘要
A recent construction showed that iteratively gauging symmetries of a quantum field theory can generate an emergent extra spatial dimension. Here we identify the precise mechanism underlying this phenomenon: it is dimensional deconstruction, the procedure by which an extra dimension is encoded in the structure of a quiver gauge theory. We demonstrate this by showing that the standard deconstruction action, upon dualizing the Goldstone fields on the Higgs branch, is exactly equivalent to the action produced by iterative gauging. The dictionary is transparent: quiver nodes correspond to gauge fields, and quiver links correspond to the gauge fields introduced to couple to magnetic symmetries. We further show that starting by gauging the electric rather than the magnetic symmetry produces the deconstructed theory written in the dual variables, with all coupling constants inverted.
