Cosmic Acceleration from Elementary Interactions
R. Aldrovandi, R. R. Cuzinatto, L. G. Medeiros
It is possible to generate an accelerated period of expansion from reasonable potentials acting between the universe particle constituents. The pressure of primordial nucleons inte…
Primeval symmetries
R. Aldrovandi, R. R. Cuzinatto, L. G. Medeiros
A detailed examination of the Killing equations in Robertson-Walker coordinates shows how the addition of matter and/or radiation to a de Sitter Universe breaks the symmetry genera…
Analytic solutions for the -FRW Model
R. Aldrovandi, R. R. Cuzinatto, L. G. Medeiros
The high precision attained by cosmological data in the last few years has increased the interest in exact solutions. Analytic expressions for solutions in the Standard Model are p…
