Observational constraints on the modified cosmology inspired by string T-duality
G. G. Luciano, A. Paliathanasis, A. Sheykhi
We explore the cosmological consequences of a modified cosmology inspired by string T-duality. We incorporate the zero-point length correction, , into the gravitational potent…
Holographic dark energy in modified Kaniadakis cosmology
A. Sheykhi, A. Asvar, E. Ebrahimi
It is well-known that any modification to the entropy expression not only change the energy density of the holographic dark energy, but also modifies the cosmological field equatio…
Constraints on Rényi Entropy through Primordial Big-Bang Nucleosynthesis and Baryogenesis
Ahmad Sheykhi, Ava Shahbazi Sooraki
The Rényi entropy, a one-parameter generalization of Boltzmann-Gibbs entropy, offers a promising framework for probing quantum gravitational effects in cosmology. By modifying the…
Big-Bang nucleosynthesis constraints on (dual) Kaniadakis cosmology
Ahmad Sheykhi, Ava Shahbazi Sooraki, Leila Liravi
We investigate the concept of Kaniadakis entropy and its dual formulation, examining their implications for gravitational dynamics within the framework where gravity emerges as an…
Horizon Entropy Refined: Quantum Contributions and Cosmological Insights
Alireza Maleki, Ahmad Sheykhi
We study the effects of quantum fluctuations on the event horizon area and their implications for corrections to the Bekenstein-Hawking entropy. These quantum corrections are incor…
