Abstract

There has been proposed two continuum descriptions of fracton systems: foliated quantum field theories (FQFTs) and exotic quantum field theories. Certain fracton systems are believed to admit descriptions by both, and hence a duality is expected between such a class of FQFTs and exotic QFTs. In this paper we study this duality in detail for concrete examples in $2+1$ and $3+1$ dimensions. In the examples, both sides of the continuum theories are of BF-type, and we find the explicit correspondences of gauge-invariant operators, gauge fields, parameters, and allowed singularities and discontinuities. This deepens the understanding of dualities in fractonic quantum field theories.

Report

In the literature, there have been two approaches to fracton models: one is based on the idea of foliated quantum field theories and the other is based on the idea of tensor gauge fields. This work explained the relations between these two approaches by demonstrating an equivalence/duality between the two in explicit examples . It spelled out in great detail how the duality works including the map on fields, operators, symmetries and the allowed singularities and discontinuities in fields.

The referee believes this work is a significant progress and will be a useful reference for the community. The referee therefore recommends the publication of this work on SciPost.

Report

The manuscript studied the correspondence between the foliated higher-form gauge theories and the tensor gauge theories using various examples. In particular, the manuscript made explicit comparisons between the singularities of the gauge fields.
