Dark Universe inspired by the Kaluza-Klein gravity and impact on Primordial Gravitational Waves
Kimet Jusufi, Giuseppe Gaetano Luciano, Ahmad Sheykhi +1
We explore the potential implications of Kaluza-Klein (KK) gravity in unifying the dark sector of the Universe. Through dimensional reduction in KK gravity, the 5D spacetime framew…
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\leq…
Modified theory in light of gravitational wave standard sirens
Mahnaz Asghari, Ahmad Sheykhi
In this paper, we ponder observational constraints on the modified gravity, where the gravitational action is a function of Ricci scalar plus the trace of the energy-m…
Holographic dark energy in Barrow cosmology with Granda-Oliveros IR cutoff
M. Motaghi, A. Sheykhi, E. Ebrahimi
Applying the modified Barrow entropy, inspired by the quantum fluctuation effects, to the cosmological background, and using thermodynamics-gravity conjuncture, the Friedmann equat…
Thermodynamical properties of nonsingular universe
Ahmad Sheykhi, Leila Liravi, Kimet Jusufi
We disclose the thermodynamical properties of the apparent horizon in a nonsingular universe. We take into account the zero-point length correction to the gravitational potential a…
Two-Field Quintessential Higgs model and the Swampland
Mehdi Es-haghi, Moslem Zarei, Ahmad Sheykhi
We study a two-field model where a quintessence field with an exponential potential is coupled to the Higgs field. It is claimed that this model is consistent with th…
