Phantom Cosmology with Non-minimally Coupled Real Scalar Field
Abstract
We find that the expansion of the universe is accelerating by analyzing the recent observation data of type Ia 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 w<-1.In this paper the possibility of using a non-minimally coupled real scalar field as phantom to realize the equation of state parameter w<-1 is discussed.The main equations which govern the evolution of the universe are obtained.Then we rewrite them with the observable quantities.
