Understand
In condensed matter physics gauge symmetries other than the U(1) of electromagnetism are of an emergent nature.
- Two emergence mechanisms for gauge symmetry are well established: the way these arise in Kramers-Wannier type local-global dualities, and as a way to encode local constraints encountered in (doped) Mott insulators.
- We demonstrate that these gauge structures are closely related, and appear as counterparts in either the canonical or field-theoretical language.
- The restoration of symmetry in a disorder phase transition is due to having the original local variables subjected to a coherent superposition of all possible topological defect configurations, with the effect that correlation functions are no longer well-defined.
