Total instanton restriction via multiverse interference: Noncompact gauge theories and (−1)
link.springer.com
When a single quantum field theory secretly decomposes into a multiverse of independent theories, the rules of instanton physics break down in ways that challenge our deepest assumptions about gauge symmetry.

Theory Briefing
- Local QFTs with noncompact gauge groups can decompose into disjoint unions of independent theories — a phenomenon called decomposition.
- Instanton contributions are totally restricted in these settings, meaning certain quantum tunneling paths are forbidden by multiverse interference effects.
- The study of (-1)-form symmetries provides the theoretical key to understanding why gauge redundancy forces this exotic multi-universe structure.
