Dilaton Coupled Quintessence Potentials

چکیده
Parametrization of the dark energy model is a good method by which we can construct the scalar potential directly from the effective equation of state function ωσ(z) describing the properties of the dark energy. Applying this method to the dilaton coupled quintessence(DCQ) model, we consider four parametrizations of ω(z) and investigate the features of the constructed DCQ potentials, which possess two different evolutive behaviors called ”O” mode and ”E” mode. Lastly, we comprise the results of the constructed DCQ model with those of quintessence model numerically.

Potentials of Coupled Quintessence Based on a Dilaton
In this paper, we regard dilaton in Weyl-scaled induced gravitational theory as coupled Quintessence, which is called DCQ model by us. Parametrization of the dark energy model is a good method by which we can construct the scalar potential directly from the effective equation of state function ωσ(z) describing the properties of the dark energy. Applying this method to the DCQ model, we consider...

In this paper, we regard dilaton in Weyl-scaled induced gravitational theory as a coupled quintessence. Based on this consideration, we investigate the dilaton coupled quintessence(DCQ) model in ω− ω plane, which is defined by the equation of state parameter for the dark energy and its derivative with respect to N(the logarithm of the scale factor a). We find the scalar field equation of motion...

متن کاملCoupled Quintessence and Phantom Based On Dilaton
Based on dilatonic dark energy model, we consider two cases: dilaton field with positive kinetic energy(coupled quintessence) and with negative kinetic energy(phantom). In the two cases, we investigate the existence of attractor solutions which correspond to an equation of state parameter ω = −1 and a cosmic density parameter Ωσ = 1. We find that the coupled term between matter and dilaton can’...
