Numerical forecasts for lab experiments constraining modified gravity: the chameleon model
Sandrine Schlogel, Sebastien Clesse, Andre Fuzfa
Current acceleration of the cosmic expansion leads to coincidence as well as fine-tuning issues in the framework of general relativity. Dynamical scalar fields have been introduced…
Beyond CDM: Problems, solutions, and the road ahead
Philip Bull, Yashar Akrami, Julian Adamek +37
Despite its continued observational successes, there is a persistent (and growing) interest in extending cosmology beyond the standard model, CDM. This is motivated by a range o…
Probing Modified Gravity with Atom-Interferometry: a Numerical Approach
Sandrine Schlogel, Sebastien Clesse, Andre Fuzfa
Refined constraints on chameleon theories are calculated for atom-interferometry experiments, using a numerical approach consisting in solving for a four-region model the static an…
K-mouflage gravity models that pass Solar System and cosmological constraints
Alexandre Barreira, Philippe Brax, Sebastien Clesse +2
We show that Solar System tests can place very strong constraints on K-mouflage models of gravity, which are coupled scalar field models with nontrivial kinetic terms that screen t…
Massive Primordial Black Holes from Hybrid Inflation as Dark Matter and the seeds of Galaxies
Sébastien Clesse, Juan García-Bellido
In this paper we present a new scenario where massive Primordial Black Holes (PBH) are produced from the collapse of large curvature perturbations generated during a mild waterfall…
An introduction to inflation after Planck: from theory to observations
Sebastien Clesse
These lecture notes have been written for a short introductory course on the status of inflation after Planck and BICEP2, given at the Xth Modave School of Mathematical Physics. Th…
