Observational constraints on fractional holographic dark energy in the light of DESI DR2
Qihong Huang, Yuchen Zhang, Bing Xu +1
Based on the fractional entropy from fractional quantum mechanics, fractional holographic dark energy (FHDE) has been proposed with the Hubble horizon as the IR cutoff (FHDEH). We…
Holographic inflation and holographic dark energy from entropy of the anti-de Sitter black hole
Qihong Huang, He Huang, Bing Xu +1
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,…
Evolution of the early universe in Einstein-Cartan theory
Qihong Huang, He Huang, Bing Xu +1
Einstein--Cartan theory is a generalization of general relativity that introduces spacetime torsion. In this paper, we perform phase space analysis to investigate the evolution of…
Constant-roll inflation and primordial black holes within Barrow entropic framework
Qihong Huang, Li-Yang Chen, He Huang +2
In this paper, starting from the modified Einstein field equations, we derive the modified scalar spectral index and the modified tensor-to-scalar ratio in Barrow entro…
CMB power spectrum in the emergent universe with k-essence
Qihong Huang, Kaituo Zhang, He Huang +2
The emergent universe provides a possible method to avoid the big bang singularity by considering that the universe stems from an stable Einstein static universe rather than the si…
Analytical approximations for primordial power spectra in a spatially closed emergent universe
Qihong Huang, Kaituo Zhang, Zhenxing Fang +1
The emergent universe scenario was proposed to solve the big bang singularity by suggesting that the universe originates from an Einstein static state and then evolves into a subse…
Cosmological perturbation and matter power spectrum in bimetric massive gravity
Chao-Qiang Geng, Chung-Chi Lee, Kaituo Zhang
We discuss the linear perturbation equations with the synchronous gauge in a minimal scenario of the bimetric massive gravity theory. We find that the matter density perturbation a…
Emergent universe in spatially flat cosmological model
Kaituo Zhang, Puxun Wu, Hongwei Yu
The scenario of an emergent universe provides a promising resolution to the big bang singularity in universes with positive or negative spatial curvature. It however remains unclea…
Oscillating universe in the DGP braneworld
Kaituo Zhang, Puxun Wu, Hongwei Yu
With a method in which the Friedmann equation is written in a form such that evolution of the scale factor can be treated as that of a particle in a "potential", we classify all po…
The stability of Einstein static universe in the DGP braneworld
Kaituo Zhang, Puxun Wu, Hongwei Yu
The stability of an Einstein static universe in the DGP braneworld scenario is studied in this paper. Two separate branches denoted by of the DGP model are analyzed. Assum…
