A noncommutative Bianchi I model with radiation
G. Oliveira-Neto, T. M. Abreu
In the present work, we study the dynamical evolution of an homogeneous and anisotropic, noncommutative (NC) Bianchi I (BI) model coupled to a radiation perfect fluid. Our first mo…
Tunneling probability for the birth of an universe with radiation in Horava-Lifshitz theory
G. Oliveira-Neto, A. Oliveira Castro Junior, G. A. Monerat
In the present work, we study the birth of a homogeneous and isotropic Friedmann Lemaitre Robertson Walker (FLRW) cosmological model, considering Horava Lifshitz (HL) as the gravit…
Tunneling probability for the birth of universes with radiation, cosmological constant and an ad hoc potential
G. Oliveira-Neto, D. L. Canedo, G. A. Monerat
In this work we study the birth of Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) models with zero () and negative () curvatures of the spatial sections. The material cont…
An anisotropic Kantowski-Sachs universe with radiation, dust and a phantom fluid
G. Oliveira-Neto, D. L. Canedo, G. A. Monerat
In the present work, we study the dynamical evolution of an homogeneous and anisotropic KS cosmological model, considering general relativity as the gravitational theory, such that…
Complete noncommutativity in a cosmological model with radiation
G. Oliveira-Neto, L. Fazza Marcon
In order to try explaining the present accelerated expansion of the universe, we consider the most complete noncommutativity, of a certain type, in a Friedmann-Robertson-Walker cos…
The effects of dark energy on the early universe with radiation and Bose-Einstein condensate
G. A. Monerat, F. G. Alvarenga, S. V. B. Gonçalves +4
This work analyzes the effects of quantization on a Friedmann-Lema\^ıtre-Robertson-Walker (FLRW) model with positive curvature and material content composed of a Bose-Einstein cond…
