Constraining Zero-Point Length from Gravitational Baryogenesis
Ava Shahbazi Sooraki, Ahmad Sheykhi
The existence of a fundamental zero-point length, , a minimal spacetime scale predicted by T-duality in string theory or quantum gravity theories, modifies the entropy associa…
Hints Beyond CDM from Barrow and Tsallis Holographic Dark Energy with GO cutoff
G. G. Luciano, A. Paliathanasis, G. Leon +2
Barrow and Tsallis Holographic Dark Energy (HDE) are two recent extensions of the standard HDE framework, obtained by introducing generalized entropy corrections through the Barrow…
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…
Emergence of the cosmic space inspired by mass-to-horizon entropy
Ahmad Sheykhi
The conception of gravity as an emergent phenomenon, rooted in the thermodynamics of spacetime, offers a radical departure from its geometric description. This paper investigates t…
Barrow Cosmology and Big-Bang Nucleosynthesis
Ahmad Sheykhi, Ava Shahbazi Sooraki
Using thermodynamics-gravity conjecture, we present the formal derivation of the modified Friedmann equations inspired by the Barrow entropy, , where $0\leqδ\le…
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…
