Cosmic infinity: A dynamical system approach
Mariam Bouhmadi-López, João Marto, João Morais +1
Dynamical system techniques are extremely useful to study cosmology. It turns out that in most of the cases, we deal with finite isolated fixed points corresponding to a given cosm…
Cosmological perturbations in an effective and genuinely phantom dark energy Universe
Imanol Albarran, Mariam Bouhmadi-López, João Morais
We carry out an analysis of the cosmological perturbations in general relativity for three different models which are good candidates to describe the current acceleration of the Un…
Towards the Quantization of Eddington-inspired-Born-Infeld Theory
Mariam Bouhmadi-López, Che-Yu Chen
The quantum effects close to the classical big rip singularity within the Eddington-inspired-Born-Infeld theory (EiBI) are investigated through quantum geometrodynamics. It is the…
Interacting 3-form dark energy models: distinguishing interactions and avoiding the Little Sibling of the Big Rip
João Morais, Mariam Bouhmadi-López, K. Sravan Kumar +2
In this paper we consider 3-form dark energy (DE) models with interactions in the dark sector. We aim to distinguish the phenomenological interactions that are defined through the…
Cosmological singularities in Eddington-inspired-Born-Infeld theory and its possible extension
Che-Yu Chen, Mariam Bouhmadi-López, Pisin Chen
The Eddington-inspired-Born-Infeld (EiBI) gravity, which is formulated within the Palatini formalism, is characterized by its ability to cure the big bang singularity in the very b…
-essence model from the mechanical approach point of view: coupled scalar field and the late cosmic acceleration
Mariam Bouhmadi-López, K. Sravan Kumar, João Marto +2
In this paper, we consider the Universe at the late stage of its evolution and deep inside the cell of uniformity. At these scales, we can consider the Universe to be filled with d…
Classical and quantum cosmology of the little rip abrupt event
Imanol Albarran, Mariam Bouhmadi-López, Claus Kiefer +2
We analyze from a classical and quantum point of view the behavior of the universe close to a little rip, which can be interpreted as a big rip sent towards the infinite future. Li…
The late Universe with non-linear interaction in the dark sector: the coincidence problem
Mariam Bouhmadi-López, João Morais, Alexander Zhuk
We study the Universe at the late stage of its evolution and deep inside the cell of uniformity. At such a scale the Universe is highly inhomogeneous and filled with discretely dis…
