The Warm Inflation Story [PDF]

open access: yesUniverse, 2023
Warm inflation has normalized two ideas in cosmology, that in the early universe the initial primordial density perturbations generally could be of classical rather than quantum origin and that during inflation, particle production from interactions ...

Warm quintessential inflation

open access: yesPhysics 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 [PDF]

open access: yesUniverse, 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 Higgs–Starobinsky inflation [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
In this work, we investigate the Higgs–Starobinsky (HS) model in the context of warm inflation scenario. The dissipative parameter as a linear form of temperature of warm inflation is considered with strong and weak regimes.

Warm deformed R2 inflation

open access: yesNuclear 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.

Reconstructing warm inflation [PDF]

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
The reconstruction of a warm inflationary universe model from the scalar spectral index $$n_S(N)$$ nS(N) and the tensor to scalar ratio r(N) as a function of the number of e-folds N is studied.

Chromonatural warm inflation [PDF]

open access: yesPhysical 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 ...

Warm inflation with Barrow holographic dark energy [PDF]

open access: yesNuclear 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 ...

Dark Matter freeze-in during warm inflation and the seesaw mechanism [PDF]

open access: yesJournal of High Energy Physics
A compelling way to address the inflationary period is via the warm inflation scenario, where the interaction of the inflaton field with other degrees of freedom affects its dynamics in such a way that slow-roll inflation is maintained by dissipative ...
