Primordial scalar power spectrum from the Euclidean Big Bounce
Susanne Schander, Aurélien Barrau, Boris Bolliet +3
In effective models of loop quantum cosmology, the holonomy corrections are associated with deformations of space-time symmetries. The most evident manifestation of the deformation…
Comparison of primordial tensor power spectra from the deformed algebra and dressed metric approaches in loop quantum cosmology
B. Bolliet, J. Grain, C. Stahl +2
Loop quantum cosmology tries to capture the main ideas of loop quantum gravity and to apply them to the Universe as a whole. Two main approaches within this framework have been con…
Restrictions on curved cosmologies in modified gravity from metric considerations
Linda Linsefors, Aurelien Barrau
This study uses very simple symmetry and consistency considerations to put constraints on possible Friedmann equations for modified gravity models in curved spaces. As an example,…
Silent initial conditions for cosmological perturbations with a change of space-time signature
Jakub Mielczarek, Linda Linsefors, Aurelien Barrau
Recent calculations in loop quantum cosmology suggest that a transition from a Lorentzian to an Euclidean space-time might take place in the very early Universe. The transition poi…
Our Universe from the cosmological constant
Aurelien Barrau, Linda Linsefors
In this article, we consider a bouncing Universe, as described for example by Loop Quantum Cosmology. If the current acceleration is due to a true cosmological constant, this const…
Exhaustive investigation of the duration of inflation in effective anisotropic loop quantum cosmology
Linda Linsefors, Aurelien Barrau
This article addresses the issue of estimating the duration in inflation in bouncing cosmology when anisotropies, inevitably playing an important role, are taken into account. It i…
