Warm inflation with an oscillatory inflaton in the non-minimal kinetic coupling model
European Physical Journal C: Particles and Fields, 2017 In the cold inflation scenario, the slow roll inflation and reheating via coherent rapid oscillation, are usually considered as two distinct eras. When the slow roll ends, a rapid oscillation phase begins and the inflaton decays to relativistic particles

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.

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 ...

Nonminimally-coupled warm Higgs inflation: Metric vs. Palatini formulations
Nuclear Physics B, 2023 In this work, we study the non-minimally-coupled Higgs model in the context of warm inflation scenario on both metric and Palatini approaches. We particularly consider a dissipation parameter of the form Γ=CTT with CT being a coupling parameter and focus

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.

Theoretical and observational prescription of warm-inflation in FLRW universe with torsion
European Physical Journal C: Particles and Fields, 2023 The paper deals with Warm Inflationary scenario in FLRW with torsion both from theoretical and observational point of view. In the background of flat FLRW model the Hubble parameter is found to be proportional to the torsion function and warm inflation ...

Does fractal universe favour warm inflation: Observational support?
Nuclear Physics B, 2022 The present work examines the possibility of warm inflationary paradigm in the modified gravity theory with fractal geometry. By choosing the normal fluid as radiation fluid and the effective fluid (with the extra term in modified field equation) as the ...
