Gravitation as a Statistical Theory on the Light Cone
José M. Isidro, Claudio F. Paganini, Alessandro Pesci
In this paper, we will explore Padmanabhan's mesoscopic, statistical approach to gravity [62] with a twist. The general picture of his approach is that spacetime is made of large n…
Theoretically motivated dark electromagnetism as the origin of relativistic MOND
Felix Finster, J. M. Isidro, Claudio F. Paganini +1
The present paper is a modest attempt to initiate the research program outlined in this abstract. We propose that general relativity and relativistic MOND (RelMOND) are analogues o…
Modified Measures as an Effective Theory for Causal Fermion Systems
Felix Finster, Eduardo Guendelman, Claudio F. Paganini
We compare the structures of the theory of causal fermion systems (CFS), an approach to unify quantum theory with general relativity (GR), with those of modified measure theories (…
A Mechanism of Baryogenesis for Causal Fermion Systems
Felix Finster, Maximilian Jokel, Claudio F. Paganini
It is shown that the theory of causal fermion systems gives rise to a novel mechanism of baryogenesis. This mechanism is worked out computationally in globally hyperbolic spacetime…
No Events on Closed Causal Curves
Claudio F. Paganini
We introduce the Causal Compatibility Conjecture for the Events, Trees, Histories (ETH) approach to Quantum Theory (QT) in the semi-classical setting. We then prove that under the…
Gravitational spin Hall effect of light
Marius A. Oancea, Jérémie Joudioux, I. Y. Dodin +3
The propagation of electromagnetic waves in vacuum is often described within the geometrical optics approximation, which predicts that wave rays follow null geodesics. However, thi…
An overview of the gravitational spin Hall effect
Marius A. Oancea, Claudio F. Paganini, Jérémie Joudioux +1
In General Relativity, the propagation of electromagnetic waves is usually described by the vacuum Maxwell's equations on a fixed curved background. In the limit of infinitely high…
Proposal 42 -- A new Storyline for the Universe based on the Causal Fermion Systems Framework
Claudio F Paganini
Based on preliminary results from the Causal Fermion Systems framework regarding the matter-antimatter asymmetry in the universe, I propose a novel story line for the universe that…
The to zero limit of spacetimes and its physical interpretation
Mark Bugden, Claudio Paganini
We study the behaviour of Schwarzschild-de Sitter spacetime and show, according to Geroch's notion of spacetime limits, that it converges to the Schwarzschild spacetime. W…
Smoothness of the future and past trapped sets in Kerr-Newman-Taub-NUT spacetimes
Claudio F. Paganini, Marius A. Oancea
We consider the sets of future/past trapped null geodesics in the exterior region of a sub-extremal Kerr-Newman-Taub-NUT spacetime. We show that, from the point of view of any time…
The Fingerprints of Black Holes - Shadows and their Degeneracies
Marc Mars, Claudio F. Paganini, Marius A. Oancea
We show that, away from the axis of symmetry, no continuous degeneration exists between the shadows of observers at any point in the exterior region of any Kerr-Newman black hole s…
Characterization of Null Geodesics on Kerr Spacetimes
Claudio F. Paganini, Blazej Ruba, Marius A. Oancea
We consider null geodesics in the exterior region of a subextremal Kerr spacetime. We show that most well-known fundamental properties of null geodesics can be represented on one p…
Mode stability on the real axis
Lars Andersson, Siyuan Ma, Claudio Paganini +1
A generalization of the mode stability result of Whiting (1989) for the Teukolsky equation is proved for the case of real frequencies. The main result of the paper states that a se…
