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)…
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…
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…
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…
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…
