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…
Observational Constraints and Cosmological Dynamics of Interacting Fractional Holographic Dark Energy in Light of DESI DR2
Qihong Huang, Hao Chen, Qingdong Wu
Based on the fractional entropy originating from fractional quantum mechanics, the fractional holographic dark energy (FHDE) model has been proposed. In this paper, we consider an…
Nearly universal CMB TT spectrum from pre-inflationary dynamics in a closed universe: KICI scenario, bouncing universe, and emergent universe
Qihong Huang, Hao Chen
We utilize the phase space analysis method to study the early evolution of the spatially closed universe and find that there exists an attractor denoting the de Sitter expansion ph…
Novel topological subclass in Hourava-Lifshitz black holes
Hao Chen, Meng-Yao Zhang, Hassan Hassanabadi +2
This work explores the universal classification of thermodynamic topology for charged static black holes within the Hourava-Lifshitz gravity theory, considering both canonica…
Agegraphic dark energy from entropy of the anti-de Sitter black hole
Qihong Huang, Yang Liu, He Huang
In this paper, we analyze the agegraphic dark energy from the entropy of the anti-de Sitter black hole using the age of the universe as the IR cutoff. We constrain its parameter wi…
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…
