Lyman-alpha power spectrum as a probe of modified gravity
Philippe Brax, Patrick Valageas
We investigate the impact of modified-gravity models on the Lyman- power spectrum. Building a simple analytical modeling, based on a truncated Zeldovich approximation, we estima…
K-mouflage Imprints on Cosmological Observables and Data Constraints
Giampaolo Benevento, Marco Raveri, Andrei Lazanu +4
We investigate cosmological constraints on K-mouflage models of modified gravity. We consider two scenarios: one where the background evolution is free to deviate from CDM (K-mo…
Gravitational Effects of Disformal Couplings
Philippe Brax, Anne-Christine Davis
We consider how a nearly massless scalar field conformally and disformally coupled to matter can affect the dynamics of gravitationally interacting bodies. We focus on the case of…
Quantum Chameleons
Philippe Brax, Sylvain Fichet
We initiate a quantum treatment of chameleon-like particles, deriving classical and quantum forces directly from the path integral. It is found that the quantum force can potential…
Interpretation of geodesy experiments in non-Newtonian theories of gravity
Joel Bergé, Philippe Brax, Martin Pernot-Borràs +1
The tests of the deviations from Newton's or Einstein's gravity in the Earth neighbourhood are tied to our knowledge of the shape and mass distribution of our planet. On the one ha…
Detecting Domain Walls in Laboratory Experiments
Claudio Llinares, Philippe Brax
The inherently unstable nature of domain walls makes their detection in laboratory experiments extremely challenging. We propose a method to stabilise domain walls in a particular…
