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. We study in detail three different classes of inflationary models, chaotic, hybrid models and hilltop models, and discuss ...

On Warm Natural Inflation and Planck 2018 Constraints
Universe, 2023 We investigate natural inflation with non-minimal coupling to gravity, characterized either by a quadratic or a periodic term, within the warm inflation paradigm during the slow-roll stage, in both strong and weak dissipation limits; and show that, in ...

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

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.

Gravitational waves from warm inflation [PDF]
Physical Review D, 2018 A fundamental prediction of inflation is a nearly scale-invariant spectrum of gravitational wave. The features of such a signal provide extremely important information about the physics of the early universe. In this paper, we focus on several topics about warm inflation.

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. The scalar fields are driven by an exponential potential and the bulk dissipative pressure coefficient is linear in the expansion rate.
