Quintessence with Coupled Scalar Fields
We discuss the dynamics of a quintessence model involving two coupled scalar fields. The model presents two types of solutions, namely solutions that correspond to eternal and transient acceleration of the universe. In both cases, we obtain values for the cosmological parameters that satisfy current...

We discuss the dynamics of a quintessence model involving two coupled scalar fields. The model presents two types of solutions, namely solutions that correspond to eternal and transient acceleration of the universe. In both cases, we obtain values for the cosmological parameters that satisfy current observational bounds as well as the nucleosynthesis constraint on the quintessence energy density. : Contribution to COSMO-01 Workshop, Rovaniemi, Finland, August 30 - September 4, 2001; 10 pages, 4 eps figures, LaTeX |
