Reconstructing the potentials for the quintessence and tachyon dark energy, from the holographic principle
نویسنده
چکیده
We propose an holographic quintessence and tachyon models of dark energy. The correspondence between the quintessence and tachyon energy densities with the holographic density, allows the reconstruction of the potentials and the dynamics for the quintessence and tachyon fields, in flat FRW background. The proposed infrared cut-off for the holographic energy density works for two cases of the constant α: for α < 1 we reconstructed the holographic quintessence model in the region before the ω = −1 crossing for the EoS parameter. The cosmological dynamics for α > 1 was also reconstructed for the holographic quintessence and tachyon models. PACS: 98.80.-k, 95.36.+x

New infrared cut-off for the holographic scalar fields models of dark energy
Introducing a new infrared cut-off for the holographic dark-energy, we study the correspondence between the quintessence, tachyon, K-essence and dilaton energy density with this holographic dark energy density in the flat FRW universe. This correspondence allows to reconstruct the potentials and the dynamics for the scalar fields models, which describe accelerated expansion. PACS: 98.80.-k, 95....
متن کاملReconstructing holographic quintessence
The holographic dark energy model is an attempt for probing the nature of dark energy within the framework of quantum gravity. The dimensionless parameter c determines the main property of the holographic dark energy. With the choice of c ≥ 1, the holographic dark energy can be described completely by a quintessence scalar field. In this paper, we show this quintessential description of the hol...

Thermodynamics second law and ω = −1 crossing(s) in interacting holographic dark energy model Abstract By the assumption that the thermodynamics second law is valid, we study the possibility of ω = −1 crossing in an interacting holographic dark energy model. Depending on the choice of the horizon and the interaction, the transition from quintessence to phantom regime and subsequently from phant...

By choosing the future event horizon as the horizon of the flat FLRW universe, we show that the interacting holographic dark energy model is able to explain the phantom divide line crossing. We show that if one takes the particle event horizon as the horizon of the universe, besides describing ω = −1 crossing, (based on astrophysical data) he is able to determine appropriately the ratio of dark...
