A late time acceleration of the universe with two scalar fields : many possibilities
arXiv:gr-qc/0605110 · doi:10.1142/S0217732306020676
Abstract
In the present work, an attempt has been made to explain the recent cosmic acceleration with two mutually interacting scalar fields, one being the Brans-Dicke scalar field and the other a quintessence scalar field. Conditions have been derived for which the quintessence scalar field has an early oscillation and it grows during a later time to govern the dynamics of the universe.
