Causality and Superluminal Fields
Jean-Philippe Bruneton
The expression of causality depends on an underlying choice of chronology. Since a chronology is provided by any Lorentzian metric in relativistic theories, there are as many expre…
The two-body problem: analytical results in a toy-model of relativistic gravity
Jean-Philippe Bruneton
The two body problem in a scalar theory of gravity is investigated. We focus on the closest theory to General Relativity (GR), namely Nordström's theory of gravity (1913). The grav…
Insight into the baryon-gravity relation in galaxies
Benoit Famaey, Gianfranco Gentile, Jean-Philippe Bruneton +1
Observations of spiral galaxies strongly support a one-to-one analytical relation between the inferred gravity of dark matter at any radius and the enclosed baryonic mass. It is ba…
On causality and superluminal behavior in classical field theories. Applications to k-essence theories and MOND-like theories of gravity
Jean-Philippe Bruneton
Field theories whose full action is Lorentz invariant (or diffeomorphism invariant) can exhibit superluminal behaviors through the breaking of local Lorentz invariance. Quantum ind…
