Modified gravity approaches to the cosmological constant problem
The FADE Collaboration, Heliudson Bernardo, Benjamin Bose +5
The cosmological constant and its phenomenology remain among the greatest puzzles in theoretical physics. We review how modifications of Einstein's general relativity could allevia…
Kalb-Ramond backgrounds in -complete cosmology
Heliudson Bernardo, Paul R. Chouha, Guilherme Franzmann
We study the matter-coupled equations of motion for cosmological NS massless fields including all corrections in an O duality invariant approach, with emphasis on the K…
Cosmology at the top of the tower
Jerome Quintin, Heliudson Bernardo, Guilherme Franzmann
The cosmology of the fully -corrected duality-invariant action for the Neveu-Schwarz sector of string theory is revisited, with special emphasis on its coupling to matter sourc…
Solution of the Size and Horizon Problems from Classical String Geometry
Heliudson Bernardo, Robert Brandenberger, Guilherme Franzmann
In a recent paper we developed a string cosmology background from classical string geometry. Here, we show that this background yields a solution to the size and horizon problems o…
String Cosmology backgrounds from Classical String Geometry
Heliudson Bernardo, Robert Brandenberger, Guilherme Franzmann
We introduce a very early universe model based on the thermodynamics of a gas of closed strings in a background which is non-perturbative in . Upon considering the fully -c…
-Cosmology: solutions and stability analysis
Heliudson Bernardo, Guilherme Franzmann
We review O Covariant String Cosmology to all orders in in the presence of matter and study its solutions. We show that the perturbative analysis for a constant dilaton…
