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.

Inflaton as a pseudo-Nambu-Goldstone boson
Physics Letters B, 2023 In the realistic model of cosmic inflation the inflaton potential should be flat and stable under quantum corrections. It is natural to imagine that there is some symmetry behind and an idea of the inflaton as a Nambu-Goldstone boson of spontaneous ...

Particle creation and warm inflation [PDF]
, 2007 During cosmological inflation, it has been suggested that fields coupled to the inflaton can be excited by the slow-rolling inflaton into a quasi-stable non-vacuum state.
