Kantoswki-Sachs model with a running cosmological constant and radiation
Vinicius G. Oliveira, Gil de Oliveira-Neto, Ilya L. Shapiro
The simplest anisotropic model of the early Universe is the one with two conformal factors, which can be identified as Kantowski-Sachs metric, or the reduced version of the Bianchi…
Qualitative and quantitative features of orbits of massive particles and photons moving in Wyman geometry
G. Oliveira-Neto, G. F. Sousa
The Wyman's solution depends on two parameters, the mass and the scalar charge . If one fixes to a positive value, say , and let take values along the real li…
The dynamics of the early universe and the initial conditions for inflation in a model with radiation and a Chaplygin gas
G. A. Monerat, G. Oliveira-Neto, E. V. Corrêa Silva +6
The modeling of the early universe is done through the quantization of a Friedmann-Robertson-Walker model with positive curvature. The material content consists of two fluids: radi…
The de Broglie-Bohm Interpretation of Evaporating Black-Holes
J. Acacio de Barros, G. Oliveira-Neto, T. B. Vale
In this work we apply the de Broglie-Bohm interpretation of quantum mechanics to the quantized spherically symmetric black-hole coupled to a massless scalar field. The wave-functio…
Scalar field cosmology in three-dimensions
G. Oliveira-Neto
We study an analytical solution to the Einstein's equations in 2+1-dimensions. The space-time is dynamical and has a line symmetry. The matter content is a minimally coupled, massl…
