Asymptotic cosmological solutions for string/brane gases with solitonic fluxes
Antonio Campos
We present new cosmological solutions for brane gases with solitonic fluxes that can dynamically explain the existence of three large spatial dimensions. This reasserts the importa…
Dynamical decompactification from brane gases in eleven-dimensional supergravity
Antonio Campos
Brane gas cosmology provides a dynamical decompactification mechanism that could account for the number of spacetime dimensions we observe today. In this work we discuss this scena…
Instant preheating mechanism and UHECR
A. H. Campos, J. M. F. Maia, R. Rosenfeld
Top-down models assume that the still unexplained Ultra High Energy Cosmic Rays (UHECR's) are the decay products of superheavy particles. Such particles may have been produced by o…
Late cosmology of brane gases with a two-form field
Antonio Campos
We consider the effects of a two-form field on the late-time dynamics of brane gas cosmologies. Assuming thermal equilibrium of winding states, we find that the presence of a form…
Late-time dynamics of brane gas cosmology
Antonio Campos
Brane gas cosmology is a scenario inspired by string theory which proposes a simple resolution to the initial singularity problem and gives a dynamical explanation for the number o…
Preheating in Quintessential Inflation
A. H. Campos, H. C. Reis, R. Rosenfeld
We perform a numerical study of the preheating mechanism of particle production in models of quintessential inflation and compare it with the usual gravitational production mechani…
