Twisting factors and fixed-time models in quantum field theory
E Vasselli - Letters in Mathematical Physics, 2024 - Springer
We construct a class of fixed-time models in which the commutations relations of a Dirac
field with a bosonic field are non-trivial and depend on the choice of a given distribution …

Where charged sectors are localizable: a viewpoint from covariant cohomology
Abstract Given a Haag–Kastler net on a globally hyperbolic spacetime, one can consider a
family of regions where quantum charges are supposed to be localized. Assuming that the …

Local Gauss law and local gauge symmetries in QFT
F Strocchi - Trails in Modern Theoretical and Mathematical Physics …, 2023 - Springer
Local gauge symmetries reduce to the identity on the observables, as well as on the
physical states (apart from reflexes of the local gauge group topology) and therefore their …

Why Gauges? Gauge symmetries for the classification of the physical states
F Strocchi - arxiv preprint arxiv:2411.01607, 2024 - arxiv.org
This note focuses the problem of motivating the use of gauge symmetries (being the identity
on the observables) from general principles, beyond their practical success, starting from …

Spontaneous Breaking of Global Gauge Symmetries in the Higgs Mechanism
S Borsboom - 2024 - philsci-archive.pitt.edu
The Higgs mechanism is invoked to explain how gauge bosons can be massive while Yang-
Mills theory describes only massless gauge fields. Central to it is the notion of spontaneous …
