LQC inverse volume corrections inflation driven by fractional power law potentials in light of ACT observations
Farough Parvizi, Kayoomars Karami
Here, we investigate the observational viability of fractional power law inflationary potentials, ( 1/3, 2/5, 2/3), within the effective framework of Loop…
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…
Structure formation in a non-canonical scalar field model of clustering dark energy
Zanyar Ebrahimi, Kayoomars Karami
This paper examines the growth of dark matter and dark energy perturbations within a non-canonical scalar field model characterized by an exponential potential. Through dynamical s…
-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…
