Hint for quintessence-like scalars from holographic dark energy
- Physics
- 2005
We use the generalized holographic dark energy model, in which both the cosmological constant (CC) and Newton’s constant GN are scale dependent, to set constraints on the renormalization-group (RG)…
HOLOGRAPHIC MODIFIED GRAVITY
- Physics
- 2008
In this paper, we investigate cosmological application of holographic dark energy density in the modified gravity framework. We employ the holographic model of dark energy to obtain the equation of…
Holographic dark energy in a cyclic universe
- Physics
- 2007
In this paper we study the cosmological evolution of the holographic dark energy in a cyclic universe, generalizing the model of holographic dark energy proposed by Li. The holographic dark energy…
Holographic dark energy in braneworld models with moving branes and the w = −1 crossing
- Physics
- 2007
We apply the bulk holographic dark energy in general 5D two-brane models. We extract the Friedmann equation on the physical brane and we show that in the general moving-brane case the effective 4D…
Interacting Holographic Dark Energy in the Scalar Gauss–Bonnet Gravity
- Physics
- 2009
We study cosmological application of interacting holographic dark energy density in the scalar Gauss–Bonnet framework. We employ the interacting holographic model of dark energy to obtain the…

The holographic dark energy in a non-flat universe
- Physics
- 2004
We study the model for holographic dark energy in a spatially closed universe, generalizing the proposal in hep-th/0403127 for a flat universe. We provide independent arguments for the choice of the…
Supernova constraints on a holographic dark energy model
- Physics
- 2004
In this paper, we use the type Ia supernova data to constrain the model of holographic dark energy. For d = 1, the best fit result is Ωm0 = 0.25, the equation of the state of the holographic dark…
Effective field theory, black holes, and the cosmological constant
- Physics
- 1999
Bekenstein has proposed the bound S{le}{pi}M{sup 2}{sub P}L{sup 2} on the total entropy S in a volume L{sup 3} . This nonextensive scaling suggests that quantum field theory breaks down in large…
FRIEDMANN–ROBERTSON–WALKER BRANE COSMOLOGICAL EQUATIONS FROM THE FIVE-DIMENSIONAL BULk (A)dS BLACK HOLE
- Physics
- 2002
In the first part of this work we review the equations of motion for the brane presented in Friedmann–Robertson–Walker (FRW) form, when the bulk is five-dimensional (A)dS Black Hole. The spacelike…
Extended holographic dark energy
- Physics
- 2004
The idea of relating the infrared and ultraviolet cutoffs is applied to the Brans-Dicke theory of gravitation. We find that the Hubble scale or the particle horizon as the infrared cutoff will not…
Observational Evidence from Supernovae for an Accelerating Universe and a Cosmological Constant
- Physics
- 1998
We present spectral and photometric observations of 10 Type Ia supernovae (SNe Ia) in the redshift range 0.16 ≤ z ≤ 0.62. The luminosity distances of these objects are determined by methods that…
