Perturbed de Sitter

Chauvineau Bertrand Fournier Jean-Daniel

The observed universe expansion features are well interpreted with the help of a cosmological term in Einstein's gravity field equations. Despite the questions raised with respect to the interpretation of a such term in the quantum field theory framework (cosmological constant = vacuum energy), the resulting model turns to be very efficient. The aim of this presentation is to explore some expected consequences resulting from this cosmological term at sub-cosmological scales.
