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 ...

Recent Developments in Warm Inflation
Universe, 2023 Warm inflation, its different particle physics model implementations, and the implications of dissipative particle production for its cosmology are reviewed.

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.

Warm Higgs–Starobinsky inflation [PDF]
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.

Warm quintessential inflation [PDF]
Physics Letters B, 2019 We introduce warm quintessential inflation and study it in the weak dissipative regime. We consider the original quintessential inflation model, which approximates quartic chaotic inflation at early times and thawing quartic inverse-power-law ...

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 ...

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.

Running and Running of the Running of the Scalar Spectral Index in Warm Inflation
Universe, 2023 The next generation of cosmological observations are expected to improve the measurements of several quantities connected to the primordial inflation in the early Universe.

Journal of High Energy PhysicsWe propose a two-field model of warm inflation motivated by a heterotic string construction, involving an axion and a dilaton-like scalar field with non-trivial kinetic mixing.

Reconstructing warm inflation [PDF]
European Physical Journal C: Particles and Fields, 2018 The reconstruction of a warm inflationary universe model from the scalar spectral index $$n_S(N)$$ nS(N) and the tensor to scalar ratio r(N) as a function of the number of e-folds N is studied.
