The role of representational conventions in assessing the empirical significance of symmetries
Henrique Gomes
This paper explicates the direct empirical significance (DES) of symmetries in gauge theory, with comparisons to classical mechanics. Given a physical system composed of subsystems…
How to Choose a Gauge? The case of Hamiltonian Electromagnetism
Henrique Gomes, Jeremy Butterfield
We develop some ideas about gauge symmetry in the context of Maxwell's theory of electromagnetism in the Hamiltonian formalism. One great benefit of this formalism is that it pairs…
Noether charges: the link between empirical significance of symmetries and non-separability
Henrique Gomes
A fundamental tenet of gauge theory is that physical quantities should be gauge-invariant. This prompts the question: can gauge symmetries have physical significance? On one hand,…
Same-diff? Conceptual similarities between gauge transformations and diffeomorphisms. Part II: Challenges to sophistication
Henrique Gomes
The following questions are germane to our understanding of gauge-(in)variant quantities and physical possibility: how are gauge transformations and spacetime diffeomorphisms under…
Same-diff? Conceptual similarities between gauge transformations and diffeomorphisms. Part I: Symmetries and isomorphisms
Henrique Gomes
The following questions are germane to our understanding of gauge-(in)variant quantities and physical possibility: how are gauge transformations and spacetime diffeomorphisms under…
Gauge Symmetries, Symmetry Breaking, and Gauge-Invariant Approaches
Philipp Berghofer, Jordan François, Simon Friederich +4
Gauge symmetries play a central role, both in the mathematical foundations as well as the conceptual construction of modern (particle) physics theories. However, it is yet unclear…
