Quintessence with Coupled Scalar Fields
M. C. Bento, O. Bertolami, N. C. Santos
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 tran…

Maximally Symmetric Cosmological Solutions of Type II Superstrings
M. C. Bento
We study maximally symmetric cosmological solutions of type II supersymmetric strings in the presence of the exact, SL(2,Z)-invariant, higher-curvature corrections to the lowest or…

On a possible solution for the Polonyi problem in string cosmology
M. C. Bento, O. Bertolami
We establish the main features of homogeneous and isotropic dilaton, metric and Yang-Mills configurations in a cosmological framework. We identify a new energy exchange term betwee…
