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…
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…
Non-Gaussianity in multiple three-form field inflation
K. Sravan Kumar, David J. Mulryne, Nelson J. Nunes +2
In this work, we present a method for implementing the formalism to study the primordial non-Gaussianity produced in multiple three-form field inflation. Using a dual descript…
-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…
