A Simple Quintessence Model
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
A simple model of quintessential inflation with the modified exponential potential is analyzed in the braneworld context. Considering reheating via instant…
Brane assisted quintessential inflation with transient acceleration
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
A simple model of quintessential inflation with the modified exponential potential exp(-αϕ) [A + (ϕ-ϕ_0)^2] is analyzed in the braneworld context. Considering reheating via instant…
Braneworld inflation from an effective field theory after WMAP three-year data
M. C. Bento, R. Gonzalez Felipe, N. M. C. Santos
In light of the results from the WMAP three-year sky survey, we study an inflationary model based on a single-field polynomial potential, with up to quartic terms in the inflaton f…
Observational constraints on modified gravity models and the Poincaré dodecahedral topology
M. C. Bento, O. Bertolami, M. J. Rebouças +1
We study the constraints that spatial topology may place on the parameters of models that account for the accelerated expansion of the universe via infrared modifications to genera…
Supernovae constraints on models of dark energy revisited
M. C. Bento, O. Bertolami, N. M. C. Santos +1
We use the Type Ia Supernova gold sample data of Riess {\it et al} in order to constrain three models of dark energy. We study the Cardassian model, the Dvali-Turner gravity modifi…
Time Evolution of the Fine Structure Constant in a Two-Field Quintessence Model
M. C. Bento, O. Bertolami, N. M. C. Santos
We examine the variation of the fine structure constant in the context of a two-field quintessence model. We find that, for solutions that lead to a transient late period of accele…
