Abstract

We investigate non-singular bounce and cyclic cosmological evolutions in a universe governed by the extended nonlinear massive gravity, in which the graviton mass is promoted to a scalar-field potential. The extra freedom of the theory can lead to certain energy conditions violations and drive cyclicity with two different mechanisms: either with a suitably chosen scalar-field potential under a given Stückelberg-scalar function, or with a suitably chosen Stückelberg-scalar function under a given scalar-field potential. Our analysis shows that extended nonlinear massive gravity can alter significantly the evolution of the universe at both early and late times.

Fluctuations in a Hořava-Lifshitz bouncing cosmology

Journal Article Gao, Xian; Wang, Yi; Xue, Wei; ... - Journal of Cosmology and Astroparticle Physics

Hořava-Lifshitz gravity is a potentially UV complete theory with important implications for the very early universe. In particular, in the presence of spatial curvature it is possible to obtain a non-singular bouncing cosmology. The bounce is realized as a consequence of higher order spatial curvature terms in the gravitational action. Here, we extend the study of linear cosmological perturbations in Hořava-Lifshitz gravity coupled to matter in the case when spatial curvature is present. As in the case without spatial curvature, we find that there is no extra dynamical degree of freedom for scalar metric perturbations. We study the evolution ofmore »« less

Open FRW universes and self-acceleration from nonlinear massive gravity

Journal Article Gümrükçüoğlu, A.; Lin, Chunshan; Mukohyama, Shinji - Journal of Cosmology and Astroparticle Physics

In the context of a recently proposed nonlinear massive gravity with Lorentz-invariant mass terms, we investigate open Friedmann-Robertson-Walker (FRW) universes driven by arbitrary matter source. While the flat FRW solutions were recently shown to be absent, the proof does not extend to the open universes. We find three independent branches of solutions to the equations of motion for the Stückelberg scalars. One of the branches does not allow any nontrivial FRW cosmologies, as in the previous no-go result. On the other hand, both of the other two branches allow general open FRW universes governed by the Friedmann equation with themore »« less

Covariant action for bouncing cosmologies in modified Gauss–Bonnet gravity

Journal Article Terrucha, Inês; Vernieri, Daniele - Annals of Physics

Cyclic universes with bouncing solutions are candidates for solving the big bang initial singularity problem. Here we seek bouncing solutions in a modified Gauss–Bonnet gravity theory, of the type R+f(G), where R is the Ricci scalar, G is the Gauss–Bonnet term, and f some function of it. In finding such a bouncing solution we resort to a technique that reduces the order of the differential equations of the R+f(G) theory to second-order equations. As general relativity is a theory whose equations are of second-order, this order reduction technique enables one to find solutions which are perturbatively close to general relativity.more »« less

Failures of homogeneous and isotropic cosmologies in extended quasidilaton massive gravity

Journal Article Anselmi, Stefano; Kumar, Saurabh; Nacir, Diana; ... - Physical Review. D.

We analyze the extended quasidilaton massive gravity model around a Friedmann-Lemaître-Robertson-Walker cosmological background. We present a careful stability analysis of asymptotic fixed points. We find that the traditional fixed point cannot be approached dynamically, except from a perfectly fine-tuned initial condition involving both the quasidilaton and the Hubble parameter. A less-well examined fixed-point solution, where the time derivative of the zeroth Stückelberg field vanishes $${\stackrel{{}}{{\phi}}}^{0}=0$$, encounters no such difficulty, and the fixed point is an attractor in some finite region of initial conditions. We examine the question of the presence of a Boulware-Deser ghost in the theory. We show thatmore »« less

Viability of the matter bounce scenario in F(T) gravity and Loop Quantum Cosmology for general potentials

Journal Article Haro, Jaume; Amorós, Jaume - Journal of Cosmology and Astroparticle Physics

We consider the matter bounce scenario in F(T) gravity and Loop Quantum Cosmology (LQC) for phenomenological potentials that at early times provide a nearly matter dominated Universe in the contracting phase, having a reheating mechanism in the expanding or contracting phase, i.e., being able to release the energy of the scalar field creating particles that thermalize in order to match with the hot Friedmann Universe, and finally at late times leading to the current cosmic acceleration. For these potentials, numerically solving the dynamical perturbation equations we have seen that, for the particular F(T) model that we will name teleparallel versionmore »« less
