Abstract

We present an alternative scheme for an Emergent Universe scenario, developed previously in Phys. Rev. D 86, 083524 (2012), where the universe is initially in a static state supported by a scalar field located in a false vacuum. The universe begins to evolve when, by quantum tunneling, the scalar field decays into a state of true vacuum. The Emergent Universe models are interesting since they provide specific examples of non-singular inflationary universes.

The Universe emerging from a vacuum in loop-string cosmology

Journal Article Mielczarek, Jakub; Szydlowski, Marek - Journal of Cosmology and Astroparticle Physics

In this paper we study a description of the Universe based on a low energy superstring theory modified by loop quantum gravity effects. This approach was proposed by De Risi et al (2007 Phys. Rev. D 76 103531). We show that in contrast with the case for a string motivated pre-big bang scenario, the cosmological realization of the t-duality transformation is not necessary to avoid an initial singularity. In the model considered, the Universe starts its evolution in the vacuum phase at time t{yields}-{infinity}. In this phase the scale factor a{yields}0, energy density {rho}{yields}0 and the coupling of the interactionsmore »« less

Instability of an emergent universe

Journal Article Mithani, Audrey; Vilenkin, Alexander - Journal of Cosmology and Astroparticle Physics

Oscillating solutions to the effective equations of Loop Quantum Cosmology have been suggested for the role of an 'eternal seed', providing a possible starting point for the emergent universe scenario. We investigate the stability of a particular model, sourced by a homogeneous massless scalar field and a negative cosmological constant, with respect to small perturbations and to quantum collapse. We find that the model has perturbatively stable and unstable solutions, with both types of solutions occupying significant regions of the parameter space. All solutions are unstable with respect to collapse by quantum tunneling to zero size. We discuss the possibilitymore »« less

Emergent universe in spatially flat cosmological model

Journal Article Zhang, Kaituo; Yu, Hongwei; Wu, Puxun - Journal of Cosmology and Astroparticle Physics

The scenario of an emergent universe provides a promising resolution to the big bang singularity in universes with positive or negative spatial curvature. It however remains unclear whether the scenario can be successfully implemented in a spatially flat universe which seems to be favored by present cosmological observations. In this paper, we study the stability of Einstein static state solutions in a spatially flat Shtanov-Sahni braneworld scenario. With a negative dark radiation term included and assuming a scalar field as the only matter energy component, we find that the universe can stay at an Einstein static state past eternally andmore »« less

The Initial State of a Primordial Anisotropic Stage of Inflation

Journal Article Blanco-Pillado, Jose; Minamitsuji, Masato - Journal of Cosmology and Astroparticle Physics

We investigate the possibility that the inflationary period in the early universe was preceded by a primordial stage of strong anisotropy. In particular we focus on the simplest model of this kind, where the spacetime is described by a non-singular Kasner solution that quickly evolves into an isotropic de Sitter space, the so-called Kasner-de Sitter solution. The initial Big Bang singularity is replaced, in this case, by a horizon. We show that the extension of this metric to the region behind the horizon contains a timelike singularity which will be visible by cosmological observers. This makes it impossible to havemore »« less
