Looking inside the Swampland from Warm Inflation: Dissipative Effects in De Sitter Expansion

Universe, 2023
This paper reviews the theoretical and phenomenological implications of the swampland conjectures from the perspective of inflationary cosmology, focusing on warm inflation.

Anisotropic warm inflation

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.

Warm Inflation with Nonminimal Derivative Coupling [PDF]

Advances in High Energy Physics, 2014
We study the effects of the nonminimal derivative coupling on the dissipative dynamics of the warm inflation where the scalar field is nonminimally coupled to gravity via its kinetic term.

Chromonatural warm inflation

Physical 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-Abelian gauge particles through the Chern-Simons term.

Minimal warm inflation [PDF]

Journal of Cosmology and Astroparticle Physics, 2020
Slow-roll inflation is a successful paradigm. However we find that even a small coupling of the inflaton to other light fields can dramatically alter the dynamics and predictions of inflation. As an example, the inflaton can generically have an axion-like coupling to gauge bosons. Even relatively small couplings will automatically induce a thermal bath

Revisiting Barrow's graduated inflationary universe: A warm perspective

Physics Letters B, 2022
It is presumed that thermal fluctuations present during inflationary epoch can make inflaton scalar field to interact with other fields resulting in the existence of a thermal component during the inflationary period.

Warm vector inflation [PDF]

Physics Letters B, 2013
In this paper we introduce the "warm vector inflation" scenario. In warm inflation scenario radiation is produced during the inflation epoch and reheating is avoided. Slow-roll and perturbation parameters of this model are presented. We develop our model using intermediate inflation model.
