Iterative Gauging is Deconstruction
arXiv:2607.26126
The paper shows that the process of iteratively gauging symmetries in a quantum field theory is exactly the same as dimensional deconstruction, with quiver nodes and links mapping to gauge fields and magnetic symmetry couplings, and discusses the dual description when gauging electric symmetries.
Abstract
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.
