[HTML][HTML] Symmetry and symmetry breaking

K Brading, E Castellani, N Teh - 2003 - plato.stanford.edu
Symmetry considerations dominate modern fundamental physics, both in quantum theory
and in relativity. Philosophers are now beginning to devote increasing attention to such …

Geometric Relational Framework for General‐Relativistic Gauge Field Theories

JT François, L Ravera - Fortschritte der Physik, 2024 - Wiley Online Library
It is recalled how relationality arises as the core insight of general‐relativistic gauge field
theories from the articulation of the generalized hole and point‐coincidence arguments …

Cartan geometry, supergravity, and group manifold approach

J François, L Ravera - arXiv preprint arXiv:2402.11376, 2024 - arxiv.org
We make a case for the unique relevance of Cartan geometry for gauge theories of gravity
and supergravity. We introduce our discussion by recapitulating historical threads, providing …

The role of fibration symmetries in geometric deep learning

O Velarde, L Parra, P Boldi, H Makse - arXiv preprint arXiv:2408.15894, 2024 - arxiv.org
Geometric Deep Learning (GDL) unifies a broad class of machine learning techniques from
the perspectives of symmetries, offering a framework for introducing problem-specific …

Note on the bundle geometry of field space, variational connections, the dressing field method, & presymplectic structures of gauge theories over bounded regions

J François, N Parrini, N Boulanger - Journal of High Energy Physics, 2021 - Springer
A bstract In this note, we consider how the bundle geometry of field space interplays with the
covariant phase space methods so as to allow to write results of some generality on the …

Unconventional Supersymmetry via the Dressing Field Method

J François, L Ravera - arXiv preprint arXiv:2412.01898, 2024 - arxiv.org
In this letter, we show that the so-called matter ansatz at the basis of the three-dimensional
model of unconventional supersymmetry by Alvarez-Valenzuela-Zanelli (AVZ) is to be …

On the Meaning of Local Symmetries: Epistemic-Ontological Dialectic

J François, L Ravera - arXiv preprint arXiv:2404.17449, 2024 - arxiv.org
We propose our account of the meaning of local symmetries. We argue that the general
covariance principle and gauge principle both are principles of democratic epistemic access …

Dressing vs. Fixing: On How to Extract and Interpret Gauge-Invariant Content

P Berghofer, J François - arXiv preprint arXiv:2404.18582, 2024 - arxiv.org
There is solid consensus among physicists and philosophers that, in gauge field theory, for a
quantity to be physically meaningful or real, it must be gauge-invariant. Yet …

The Fröhlich–Morchio–Strocchi Mechanism: An Underestimated Legacy

A Maas - Trails in Modern Theoretical and Mathematical Physics …, 2023 - Springer
There is an odd tension in electroweak physics. Perturbation theory is extremely successful.
At the same time, fundamental field theory gives manifold reasons why this should not be the …
