Warm-assisted natural inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Abstract We consider natural inflation in a warm inflation framework with a temperature-dependent dissipative coefficient Γ∝ T3. Natural inflation can be compatible with the Planck 2018 results with such warm assistance. With no a priori assumptions on the dissipative effect's magnitude, we find that the Planck results prefer a weak ...

Warming up cold inflation [PDF]
Journal of Cosmology and Astroparticle Physics, 2021 Abstract The axion is a well-motivated candidate for the inflaton, as the radiative corrections that spoil many single-field models are avoided by virtue of its shift symmetry. However, axions generically couple to gauge sectors. As the axion slow-rolls during inflation, this coupling can cause the production of a non-diluting thermal ...

Intermediate class of warm pseudoscalar inflation
European Physical Journal C: Particles and Fields, 2021 High dissipative regime of warm pseudoscalar inflation model (Kamali in Phys Rev D 100:043520, arXiv:1901.01897 [gr-qc], 2019) with an approximately constant value of dissipation parameter Q is studied.

Constraints of Anisotropy on Warm Power-Law Ination in Light of Planck Results [PDF]
Iranian Journal of Astronomy and Astrophysics, 2021 In this article, we examine the effects of anisotropy on a model of canonical warm inflation with the power-law potential. And we have compared the limitations of this model with Planck's results.

Physics Letters B, 2012 In warm inflation models there is the requirement of generating large dissipative couplings of the inflaton with radiation, while at the same time, not de-stabilising the flatness of the inflaton potential due to radiative corrections. One way to achieve this without fine tuning unrelated couplings is by supersymmetry. In this paper we show that if the

Physical Review D, 2023 Anisotropic inflation is a model succeeded in explaining statistical anisotropy. Warm inflation is a model succeeded in providing a mechanism of reheating during inflation. We study anisotropic warm inflation focusing on the cosmic no-hair conjecture. In the anisotropic warm inflation, the condition for making anisotropy survived is clarified.

Salvaging power-law inflation through warming
European Physical Journal C: Particles and Fields, 2023 Power-law inflation with scale factor $$a \propto t^m$$ a ∝ t m is investigated in the context of warm inflation. The treatment is performed in the weak and strong dissipation limits.
