Article overview

An interacting scalar field and the recent cosmic acceleration
Sudipta Das ; Narayan Banerjee ;
Date:	27 Jul 2005
Subject:	gr-qc
Abstract:	In this paper it is shown that the Brans - Dicke scalar field itself can serve the purpose of providing an early deceleration and a late time acceleration of the universe without any need of quintessence field if one considers an interaction, i.e, transfer of energy between the dark matter and the Brans - Dicke scalar field.
