Abstract It is extraordinary that a number of observations indicate that we live in a spatially flat, low matter density Universe, which is currently undergoing a period of accelerating expansion. The effort to explain this current state has focused attention on cosmological models in which the dominant component of the cosmic energy density has negative pressure, with an equation of state w⩾−1. Remarking that most observations are consistent with models right up to the w=−1 or cosmological… Expand

Effective equation of state for dark energy: Mimicking quintessence and phantom energy through a variable Λ
Abstract While there is mounting evidence in all fronts of experimental cosmology for a non-vanishing dark energy component in the Universe, we are still far away from understanding its ultimateExpand
Cosmological evolution of a quintom model of dark energy

Cosmological Evolution of a Tachyon-Quintom Model of Dark Energy
In this work we study the cosmological evolution of a dark energy model with two scalar fields, i.e. the tachyon and the phantom tachyon. This model enables the equation of state w to change from w >Expand
Accelerating Hilbert-Einstein universe without dynamic dark energy
By using an unmodified Einstein gravity theory it is shown that all of the speeding-up effects taking place in the current universe are entirely due to the quantum effects associated with theExpand
Dynamical relaxation of dark energy: A solution to early inflation, late-time acceleration and the cosmological constant problem
Abstract In recent years different explanations are provided for both an inflation and a recent acceleration in the expansion of the universe. In this Letter we show that a model of physical interestExpand

On the equation of state of dark energy
Abstract The formalism in order to obtain the dark energy equation of state is extended to non-flat universes and we consider the inequalities that must be satisfied by phantom dark energy in thisExpand
Pressure anisotropy and dark energy models in scale invariant theory of gravitation

Cosmological imprint of an energy component with general equation of state
We examine the possibility that a significant component of the energy density of the Universe has an equation of state different from that of matter, radiation, or cosmological constant ({Lambda} ).Expand
Dynamical solution to the problem of a small cosmological constant and late-time cosmic acceleration
In the theories considered, the dynamics causes the scalar field to lock automatically into a negative pressure state at the onset of matter domination such that the present epoch is the earliest possible time consistent with nucleosynthesis restrictions when it can start to dominate. Expand
