Time evolution of the equation of state during perturbative reheating and its impact on the inflationary tensor perturbation spectrum

Nuclear Physics B
The spectrum of inflationary tensor perturbations is one of the very few available probes of the post-inflationary reheating epoch, and it is strongly influenced by the Universe's equation of state during this period.

de Sitter symmetries and inflationary scalar-vector models

Universitas Scientiarum, 2016
In this paper, we study the correspondence between a field theory in de Sitter space in D-dimensions and a dual conformal field theory in a euclidean space in (D − 1)-dimensions.

Preinflationary Dynamics of Power-Law Potential in Loop Quantum Cosmology †

Universe, 2018
In this article, I mainly discuss the dynamics of the pre-inflationary Universe for the potential V ( ϕ ) ∝ ϕ n with n = 5 / 3 in the context of loop quantum cosmology, in which the big bang singularity is resolved by a non ...

Universal features of quantum bounce in loop quantum cosmology

Physics Letters B, 2017
In this Letter, we study analytically the evolutions of the flat Friedmann–Lemaitre–Robertson–Walker (FLRW) universe and its linear perturbations in the framework of the dressed metric approach in loop quantum cosmology (LQC). Assuming that the evolution
