Holographic inflation and holographic dark energy from entropy of the anti-de Sitter black hole
Abstract Based on the entropy of anti-de Sitter black hole, a new holographic dark energy model has been proposed. When the Hubble horizon and particle horizon are chosen as the IR cutoff, the late-time accelerated expansion of universe is realized. In this paper, we consider the Hubble horizon as t...

| description | Abstract Based on the entropy of anti-de Sitter black hole, a new holographic dark energy model has been proposed. When the Hubble horizon and particle horizon are chosen as the IR cutoff, the late-time accelerated expansion of universe is realized. In this paper, we consider the Hubble horizon as the IR cutoff to investigate holographic inflation and slow-roll inflation in this model. We find that slow-roll inflation with the chaotic potential $$V_{0}\phi ^{n}$$ V 0 ϕ n is favored by Planck results for some special cases, such as $$n=1/3$$ n = 1 / 3 and $$n=1/2$$ n = 1 / 2 , while holographic inflation is not supported by Planck results. Then, we analyze the reheating temperature and the number of reheating e-folds in this model, and we find that the results favor the cases $$n=1/3$$ n = 1 / 3 and $$n=1/2$$ n = 1 / 2 . Finally, we use the dynamical analysis method, statefinder diagnostic pairs, and the Hubble diagram to analyze this model. Our results indicate that when $$b^{2}$$ b 2 takes a small value, this model cannot be distinguished from the standard $$\Lambda $$ Λ CDM model and can serve as an alternative to it. |
