Universe, 2023 Warm inflation has normalized two ideas in cosmology, that in the early universe the initial primordial density perturbations generally could be of classical rather than quantum origin and that during inflation, particle production from interactions ...

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 ...

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.

Nuclear Physics B, 2023 In this work, we study warm inflationary scenario based on a deformation of R2 gravity. We start considering Rp and assume p=2(1+δ) with δ≪1 so that we simply obtain warm R2 inflation when setting δ=0.

Warm Higgs–Starobinsky inflation
European Physical Journal C: Particles and Fields, 2022 In this work, we investigate the Higgs–Starobinsky (HS) model in the context of warm inflation scenario. The dissipative parameter as a linear form of temperature of warm inflation is considered with strong and weak regimes.

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.

Universe, 2016 I show here that there are some interesting differences between the predictions of warm and cold inflation models focusing in particular upon the scalar spectral index n s and the tensor-to-scalar ratio r.

Strengthening the de Sitter swampland conjecture in warm inflation
Journal of High Energy Physics, 2020 The de Sitter constraint on the space of effective scalar field theories consistent with superstring theory provides a lower bound on the slope of the potential of a scalar field which dominates the evolution of the Universe, e.g., a hypothetical ...
