Could there exist gauge-symmetry-protected topological order?
More precisely, let $\hat{H}_1, \hat{H}_2$ be locally-interacting, translation-invariant quantum many-body Hamiltonians (defined on the same quantum system) that both has a gauge symmetry $G$, and ...

Properties of Topologically Ordered States
From what I've read so far, all topologically ordered states seem to possess the following properties:
Gapped excitations with fractionalized statistics (anyons)
Gauge theory structure (which may be &...

On string-like excitations in (3+1)d discrete gauge theory
(3+1)d discrete $G$-gauge theory (untwisted Dijkgraaf-Witten theory) has both point-like and loop-like excitations;
Point-like excitation is an electric charge labeled by an irreducible ...
