The Non-Relativistic Geometric Trinity of Gravity
William J. Wolf, James Read, Quentin Vigneron
The geometric trinity of gravity comprises three distinct formulations of general relativity: (i) the standard formulation describing gravity in terms of spacetime curvature, (ii)…
Underdetermination in Classic and Modern Tests of General Relativity
William J. Wolf, Marco Sanchioni, James Read
Canonically, `classic' tests of general relativity (GR) include perihelion precession, the bending of light around stars, and gravitational redshift; `modern' tests have to do with…
Tachyonic media in analogue models of special relativity
Sundance O. Bilson-Thompson, Scott L. Todd, James Read +2
In sonic models of special relativity, the fact that the sonic medium violates (ordinary) Lorentz symmetry is apparent to observers external to the sonic medium but not to a class…
Abnormal light propagation and the underdetermination of theory by evidence in astrophysics
Felipe A. Asenjo, Sergio A. Hojman, Niels Linnemann +1
We investigate the propagation of certain non-plane wave solutions to Maxwell's equations in both flat and curved spacetimes. We find that such solutions (or rather parts of them)…
Respecting Boundaries: Theoretical Equivalence and Structure Beyond Dynamics
William J. Wolf, James Read
A standard line in the contemporary philosophical literature has it that physical theories are equivalent only when they agree on their empirical content, where this empirical cont…
Constructive Axiomatics in Spacetime Physics Part II: Constructive Axiomatics in Context
Emily Adlam, Niels Linnemann, James Read
The Ehlers-Pirani-Schild (EPS) constructive axiomatisation of general relativity, published in 1972, purports to build up the kinematical structure of that theory from only axioms…
Constructive Axiomatics in Spacetime Physics Part III: A Constructive Axiomatic Approach to Quantum Spacetime
Emily Adlam, Niels Linnemann, James Read
The Ehlers-Pirani-Schild (EPS) constructive axiomatisation of general relativity, published in 1972, purports to build up the kinematical structure of that theory from only axioms…
Constructive Axiomatics in Spacetime Physics Part I: Walkthrough to the Ehlers-Pirani-Schild Axiomatisation
Niels Linnemann, James Read
The Ehlers-Pirani-Schild (EPS) constructive axiomatisation of general relativity, published in 1972, purports to build up the kinematical structure of that theory from only axioms…
Edge modes and dressing fields for the Newton-Cartan quantum Hall effect
William J. Wolf, James Read, Nicholas Teh
It is now well-known that Newton-Cartan theory is the correct geometrical setting for modelling the quantum Hall effect. In addition, in recent years edge modes for the Newton-Cart…
Comment on `Do electromagnetic waves always propagate along null geodesics?'
Niels Linnemann, James Read
We study the propagation of Maxwellian electromagnetic waves in curved spacetimes in terms of the appropriate geometrical optics limit, notions of signal speed, and minimal couplin…
Dessins d'Enfants, Seiberg-Witten Curves and Conformal Blocks
Jiakang Bao, Omar Foda, Yang-Hui He +4
We show how to map Grothendieck's dessins d'enfants to algebraic curves as Seiberg-Witten curves, then use the mirror map and the AGT map to obtain the corresponding 4d $\mathcal{N…
Conformal Invariance of the Newtonian Weyl Tensor
Neil Dewar, James Read
It is well-known that the conformal structure of a relativistic spacetime is of profound physical and conceptual interest. In this note, we consider the analogous structure for New…
The Teleparallel Equivalent of Newton-Cartan Gravity
James Read, Nicholas Teh
We construct a notion of teleparallelization for Newton-Cartan theory, and show that the teleparallel equivalent of this theory is Newtonian gravity; furthermore, we show that this…
Yang-Mills Theory and the ABC Conjecture
Yang-Hui He, Zhi Hu, Malte Probst +1
We establish a precise correspondence between the ABC Conjecture and N=4 super-Yang-Mills theory. This is achieved by combining three ingredients: (i) Elkies' method of mapping ABC…
Clarifying possible misconceptions in the foundations of general relativity
Harvey R. Brown, James Read
We discuss what we take to be three possible misconceptions in the foundations of general relativity, relating to: (a) the interpretation of the weak equivalence principle and the…
Dessins d'Enfants in Generalised Quiver Theories
Yang-Hui He, James Read
We study Grothendieck's dessins d'enfants in the context of the supersymmetric gauge theories in dimensions with product gauge…
Hecke Groups, Dessins d'Enfants and the Archimedean Solids
Yang-Hui He, James Read
Grothendieck's dessins d'enfants arise with ever-increasing frequency in many areas of 21st century mathematical physics. In this paper, we review the connections between dessins a…
Modular Subgroups, Dessins d'Enfants and Elliptic K3 Surfaces
Yang-Hui He, John McKay, James Read
We consider the 33 conjugacy classes of genus zero, torsion-free modular subgroups, computing ramification data and Grothendieck's dessins d'enfants. In the particular case of the…
