Revisited apparent horizon entropy and GSL in modified gravity
Soma Heydari, Parastoo Askari, Kayoomars Karami
This work presents a universal and revisited formalism for the entropy of the apparent horizon in modified gravity to investigate the validity of the Generalized Second Law (GSL) o…
Reheating and relic gravitational waves as remedies for degeneracies of non-canonical natural inflation
Karam Bahari, Soma Heydari, Kayoomars Karami
Here, a natural non-canonical inflationary model based on a power-law Lagrangian is investigated. We analyze the scalar spectral index and the tensor-to-scalar ratio $r…
Mutated hilltop inflation in light of Planck/ACT observations
Iraj Safaei, Soma Heydari, Milad Solbi +1
Here, a single field inflationary model driven by a mutated hilltop potential, a subclass of the hilltop models of inflation, is investigated. To constrain the parameter space, we…
-attractor inflation modified by GUP in light of ACT observations
Hana Heidarian, Milad Solbi, Soma Heydari +1
Here, the -attractor inflation is investigated within a framework incorporating a minimal measurable length, as implemented by the Generalized Uncertainty Principle (GUP). The…
Loop quantum inflation with inverse volume corrections in light of ACT data
Farough Parvizi, Soma Heydari, Milad Solbi +1
Within the framework of loop quantum cosmology (LQC), we investigate the effect of inverse volume corrections on the low scale spontaneously broken supersymmetric (SB SUSY) and exp…
Primordial black holes in SB SUSY Gauss-Bonnet inflation
A. Ashrafzadeh, M. Solbi, S. Heydari +1
Here, we explore the formation of primordial black holes (PBHs) within a scalar field inflationary model coupled to the Gauss-Bonnet (GB) term, incorporating the low-scale spontane…
