Quintessence and supergravity
Philippe Brax,Jérôme Martin +1 more
TL;DR: In this paper, the scalar potential of the supergravity model has been shown to have the form V(Q)= Λ 4+α Q α e κ 2 Q 2.
Journal ArticleDOI
Cosmology and brane worlds: a review
TL;DR: In this article, the authors reviewed the consequences of the brane world cosmology in a pedagogical manner and investigated the cosmology of a system with two branes and a bulk scalar field.
Journal ArticleDOI
Brane world cosmology
TL;DR: In this article, the authors review cosmological aspects of brane world scenarios such as the Randall-Sundrum brane model and two-brane systems with a bulk scalar field.
Journal ArticleDOI
Unified description of screened modified gravity
TL;DR: In this article, the authors consider modified gravity models driven by a scalar field whose effects are screened in high density regions due to the presence of nonlinearities in its interaction potential and/or its coupling to matter.
Journal ArticleDOI
Systematic Simulations of Modified Gravity: Symmetron and Dilaton Models
TL;DR: In this paper, the effects of modified gravity on the matter power spectrum and mass function have been investigated using the N-body simulation code ECOSMOG, which is a variant of RAMSES working in modified gravity scenarios and performed a set of 110 simulations for different models and parameter values, including the default ΛCDM.
