چکیده

We discuss the anthropic principle when applied to the holographic dark energy. We find that if the amplitude of the density fluctution is variable, the holographic dark energy fares better than the cosmological constant.

2 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.

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...

Constraints 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...

Holographic Dark Information Energy

Landauer’s principle and the Holographic principle are used to derive the holographic information energy contribution to the Universe. Information energy density has increased with star formation until sufficient to start accelerating the expansion of the universe. The resulting reduction in the rate of star formation due to the accelerated expansion may provide a feedback that limits the infor...

Se p 20 06 Interacting holographic dark energy model in non - flat universe

We employ the holographic model of interacting dark energy to obtain the equation of state for the holographic energy density in non-flat (closed) universe enclosed by the event horizon measured from the sphere of horizon named L.
