On the Vacuum Energy in Expanding Space-Times
If there is a shortest length in nature, for example at the Planck scale of 10m, then the cosmic expansion should continually create new comoving modes. A priori, each of the new modes comes with its own vacuum energy, which could contribute to the cosmological constant. I discuss possible mathematical models for a shortest length and an explicit model for a corresponding mode-generating mechan...
متن کاملInteracting 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.
متن کاملThe Holographic Dark Energy in a Non-flat Universe
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 parameter c = 1 in the holographic dark energy model. On the one hand, c can not be less than 1, to avoid violating the second law of thermodynamics. On the other hand, observation suggests c be ver...
متن کاملThe holographic dark energy in non - flat Brans - Dicke cosmology
In this paper we study cosmological application of holographic dark energy density in the Brans-Dicke framwork. We employ the holographic model of 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. Our calculation show, taking Ω Λ = 0.73 for the present time, the ...
متن کاملDark Energy From Vacuum Fluctuations
The nature of the dark energy (DE) is one of the most outstanding problems of physical sciences today. Numerous and often ingenious attempts have been made to explain it, with multiple new papers appearing daily, yet no model proposed so far has gained a general acceptance. Modern approaches to the problem date from the pioneering papers by Zel’dovich [1], who was first to recognize the fundame...
