Natural Warm Inflation [PDF]

Journal of Cosmology and Astroparticle Physics, 2011
We derive the requirements that a generic axion-like field has to satisfy in order to play the role of the inflaton field in the warm inflation scenario.

On Perturbations in Warm Inflation [PDF]

Physical Review D, 2001
Warm inflation is an interesting possibility of describing the early universe, whose basic feature is the absence, at least in principle, of a preheating or reheating phase.

Warm Inflation [PDF]

Universe, 2016
I show here that there are some interesting differences between the predictions of warm and cold inflation models focusing in particular upon the scalar spectral index n s and the tensor-to-scalar ratio r.

Warm deformed R2 inflation

Nuclear Physics B, 2023
In this work, we study warm inflationary scenario based on a deformation of R2 gravity. We start considering Rp and assume p=2(1+δ) with δ≪1 so that we simply obtain warm R2 inflation when setting δ=0.

Warm quintessential inflation

Physics Letters B, 2019
We introduce warm quintessential inflation and study it in the weak dissipative regime. We consider the original quintessential inflation model, which approximates quartic chaotic inflation at early times and thawing quartic inverse-power-law ...

Warm inflation model building [PDF]

International Journal of Modern Physics A, 2009
We review the main aspects of the warm inflation scenario, focusing on the inflationary dynamics and the predictions related to the primordial spectrum of perturbations, to be compared with the recent cosmological observations.

Chromonatural warm inflation [PDF]

Physical Review D
Chromonatural inflation is a model where non-Abelian gauge fields are sustained by the coupling of the axion with the gauge field through the Chern-Simons term, while minimal warm inflation is a model where the axion produces a thermal bath of non ...

Synergistic warm inflation [PDF]

Physical Review D, 2002
We consider an alternative warm inflationary scenario in which $n$ scalar fields coupled to a dissipative matter fluid cooperate to produce power--law inflation.

Warm inflation with Barrow holographic dark energy [PDF]

Nuclear Physics B
In this work we study the warm inflation mechanism in the presence of the Barrow holographic dark energy model. Warm inflation differs from other forms of inflation primarily in that it assumes that radiation and inflaton fields exist and interact ...

Non-minimal Higgs inflation in the context of warm scenario in the light of Planck data

European Physical Journal C: Particles and Fields, 2018
We investigate the non-minimally Higgs inflaton (HI) model in the context of warm inflation scenario. Warm little inflaton (WLI) model considers the little Higgs boson as inflaton.
