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…
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…
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,…
Testing the cosmic distance duality relation using Type Ia supernovae and BAO observations
Fan Yang, Xiangyun Fu, Bing Xu +3
In this work, we propose to utilize the observed ratio of spherically-averaged distance to the sound horizon scale from Baryon Acoustic Oscillation (BAO) data to test the cosmic di…
