An Alternative Approach to Holographic Dark Energy
نویسنده
چکیده
We outline a scenario in which dark energy is associated with the particle horizon. An energy density related to the area of the particle horizon is found to behave in accordance with current observational constraints. The equation of state drops as the particle horizon traverses a closed universe. Depending on the constant of proportionality, either the ensuing inflationary period prevents the particle horizon from vanishing, or it may lead to a sequence of “Big Rips”.

An Interacting Dark Energy Model for the Expansion History of the Universe
We explore a model of interacting dark energy where the dark energy density is related by the holographic principle to the Hubble parameter, and the decay of the dark energy into matter occurs at a rate comparable to the current value of the Hubble parameter. We find this gives a good fit to the observational data supporting an accelerating Universe, and the model represents a possible alternat...
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...
متن کاملA Dynamic Dark Information Energy Consistent with Planck Data
The 2013 cosmology results from the European Space Agency Planck spacecraft provide new limits to the dark energy equation of state parameter. Here we show that Holographic Dark Information Energy (HDIE), a dynamic dark energy model, achieves an optimal fit to the published datasets where Planck data is combined with other astrophysical measurements. HDIE uses Landauer’s principle to account fo...
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 کاملBeyond ɅCDM: a viable alternative?
We are encouraged to look beyond ɅCDM as there are no satisfactory explanations for either dark energy or dark matter. A data centred phenomenological approach supports an explanation where dark energy is Holographic Dark Information Energy, HDIE. HDIE explains many effects attributed separately to Ʌ and CDM. HDIE mimics Ʌ with sufficient energy and an equation of state parameter, w= -1.03±0.05...
