Phantom Cosmology with Non-minimally Coupled Real Scalar Field
arXiv:gr-qc/0410096 · doi:10.1007/s10714-005-0014-2
Abstract
We find that the expansion of the universe is accelerating by analyzing the recent observation data of type $\textsc{I}a$ supernova(SN-Ia) .It indicates that the equation of state of the dark energy might be smaller than -1,which leads to the introduction of phantom models featured by its negative kinetic energy to account for the regime of equation of state parameter .In this paper the possibility of using a non-minimally coupled real scalar field as phantom to realize the equation of state parameter is discussed.The main equations which govern the evolution of the universe are obtained.Then we rewrite them with the observable quantities.
