A Model of Holographic Dark Energy
نویسنده
چکیده
A model for holographic dark energy is proposed, following the idea that the short distance cut-off is related to the infrared cut-off. We assume that the infrared cut-off relevant to the dark energy is the size of the event horizon. With the input ΩΛ = 0.73, we predict the equation of state of the dark energy at the present time be characterized by w = −0.90. The cosmic coincidence problem can be resolved by inflation in our scenario, provided we assume the minimal number of e-foldings.

Statefinder diagnosis for the interacting model of holographic dark energy
In this paper, we investigate the holographic dark energy model with interaction between dark energy and dark matter, from the statefinder viewpoint. We plot the trajectories of the interacting holographic dark energy model for different interaction cases as well as for different values of the parameter c in the statefinder-plane. The statefinder diagrams characterize the properties of the holo...
متن کاملConstraints on holographic dark energy from Type Ia supernova observations
In this paper, we use the Type Ia supernovae data to constrain the holographic dark energy model proposed by Li. We also apply a cosmic age test to this analysis. We consider in this paper a spatially flat FRW universe with matter component and holographic dark energy component. The fit result shows that the case c < 1 is favored, which implies that the holographic dark energy behaves as a quin...
متن کاملHolographic Dark Energy Model with Modified Generalized Chaplygin Gas
We present a holographic dark energy model of the universe considering modified generalized Chaplygin gas (GCG). The modified GCG behaves as an ordinary barotropic fluid in the early epoch when the universe was tiny but behaves subsequently as a ΛCDM model at late epoch. An equivalent model with scalar field is obtained here by constructing the corresponding potential. The holographic dark ener...
متن کاملStatefinder diagnostic for holographic dark energy model
In this paper we study the holographic dark energy model proposed by Li from the statefinder viewpoint. We plot the evolutionary trajectories of the model with c = 1 in the statefinder parameter-planes. The statefinder diagrams characterize the properties of the holographic dark energy and show the discrimination between this scenario and other dark energy models. We also perform a statefinder ...
متن کاملHolographic Dark Energy Model with Generalized Chaplygin Gas
We present a holographic dark energy model of the universe considering modified extension of the generalized Chaplygin gas (GCG). The modified GCG behaves as an ordinary barotropic fluid in the early epoch when the universe was tiny but behaves subsequently as a ΛCDMmodel as the universe grows. We determine the corresponding holographic dark energy field and its potential. The stability of the ...
متن کامل2 00 7 Interacting Holographic Phantom
In this paper we consider the holographic model of interacting dark energy in non-flat universe. With the choice of c ≤ 0.84, the interacting holographic dark energy can be described by a phantom scalar field. Then we show this phantomic description of the holographic dark energy with c ≤ 0.84 and reconstruct the potential of the phantom scalar field.
