Higher Dressing and Shift-Invariance in 4D Topological BF Theory
J. François, L. Ravera
A characteristic feature of topological field theories is the absence of local propagating degrees of freedom. In four-dimensional BF theory with cosmological term, we make this fe…
Toward Manifest Relationality in Transformers via Symmetry Reduction
J. François, L. Ravera
Transformer models contain substantial internal redundancy arising from coordinate-dependent representations and continuous symmetries, in model space and in head space, respective…
Torsional Carroll Gravity
P. Concha, N. Merino, L. Ravera +1
The ultra-relativistic (Carrollian) regime of gravity has recently emerged as a fertile framework for exploring holography, non-Lorentzian symmetries, and geometric limit of Genera…
Raising galaxy rotation curves via dressing
J. François, L. Ravera
We present a manifestly diffeomorphism-invariant simple model of galaxy dynamics obtained by applying the Dressing Field Method (DFM) to a general-relativistic system comprising th…
Mechanics as a general-relativistic gauge field theory, and Relational Quantization
J. François, L. Ravera
We treat the Mechanics of point particles as a 1-dimensional general-relativistic gauge field theory, which may be referred to as Mechanical Field Theory (MFT), exploiting the bund…
What Price Fiber Bundle Substantivalism? On How to Avoid Holes in Fibers
Philipp Berghofer, Jordan François, Lucrezia Ravera
On a mathematically foundational level, our most successful physical theories (gauge field theories and general-relativistic theories) are formulated in a framework based on the di…
Reassessing the foundations of Metric-Affine Gravity
J. François, L. Ravera
We reassess foundational aspects of Metric-Affine Gravity (MAG) in light of the Dressing Field Method, a tool allowing to systematically build gauge-invariant field variables. To g…
Spacetime boundaries do not break diffeomorphism and gauge symmetries
J. François, L. Ravera
In General Relativity and gauge field theory, one often encounters a claim, which may be called the boundary problem, according to which "boundaries break diffeomorphism and gauge…
Off-shell supersymmetry via manifest invariance
J. François, L. Ravera
A fundamental challenge in supersymmetric field theory is that supersymmetry transformations on field variables generally form an algebra only on-shell, i.e. upon imposing the fiel…
Relational Supersymmetry via the Dressing Field Method and Matter-Interaction Supergeometric Framework
J. François, L. Ravera
Relationality is the paradigmatic conceptual core of general-relativistic gauge field theory. It can be made manifest via the Dressing Field Method (DFM) of symmetry reduction, a s…
Relational bundle geometric formulation of non-relativistic quantum mechanics
J. François, L. Ravera
We present a bundle geometric formulation of non-relativistic many-particles Quantum Mechanics. A wave function is seen to be a -valued cocyclic tensorial 0-form on con…
Unconventional Supersymmetry via the Dressing Field Method
J. François, L. Ravera
We re-construe unconventional supersymmetry, a notion introduced by Alvarez-Valenzuela-Zanelli (AVZ), as an attempt to use the framework of supersymmetric field theory to describe…
Boson-fermion algebraic mapping in second quantization
F. Lingua, D. M. Peñafiel, L. Ravera +1
We present an algebraic method to derive the structure at the basis of the mapping of bosonic algebras of creation and annihilation operators into fermionic algebras, and vice vers…
Geometric relational framework for general-relativistic gauge field theories
Jordan François, Lucrezia Ravera
We remind how relationality arises as the core insight of general-relativistic gauge field theories from the articulation of the generalised hole and point-coincidence arguments. H…
Dressing fields for supersymmetry: The cases of the Rarita-Schwinger and gravitino fields
J. François, L. Ravera
In this paper we argue that the gauge-fixing conditions typically used to extract the (off-shell) degrees of freedom of the Rarita-Schwinger spinor-vector and gravitino, respective…
On the Meaning of Local Symmetries: Epistemic-Ontological Dialectics
Jordan François, Lucrezia Ravera
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 to…
Cartan geometry, supergravity, and group manifold approach
J. François, L. Ravera
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, providi…
