No warm inflation from a vanilla axion

Physical Review D
At finite temperature, the coupling of an axion to non-Abelian gauge fields causes dissipation due to sphaleron heating. This mechanism has been considered as ideal for realizing warm inflation, since it can lead to large thermal friction while ...

Dark Matter Production during Warm Inflation via Freeze-In.

Physical Review Letters
We present a novel perspective on the role of inflation in the production of dark matter (DM). Specifically, we explore the DM production during warm inflation via ultraviolet freeze-in (WIFI).

Stage IV CMB forecasts for warm inflation

Journal of Cosmology and Astroparticle Physics
We report forecast constraints on warm inflation in the light of future cosmic microwave background (CMB) surveys, with data expected to be available in the coming decade.

New limits on warm inflation from pulsar timing arrays

Physics of the Dark Universe
In this paper, we investigate scalar-induced gravitational waves (GWs) generated in the post-inflationary universe to infer new limits on warm inflation.

Loosely coupled particles in warm inflation

Journal of Cosmology and Astroparticle Physics
Cosmological perturbations in warm inflation are conventionally described by an EFT. It consists of the inflaton field coupled to a radiation fluid and applies to energy scales of order Hubble H and inflaton decay width γ, but well below temperature T ...

Warm inflation triggered by entropies of some recent dark energy models within gravity

Chinese Physics C, High Energy Physics & Nuclear Physics
This manuscript aims to study cosmic warm inflation (WI) in the framework of - gravity, where Q represents the nonmetricity (NM) scalar. To accomplish this task, we introduce the Tsallis, Renyi, and Barrow holographic dark energy (HDE) entropies into the

Warm inflation and WMAP9

International Journal of Geometric Methods in Modern Physics, 2017
A warm inflation model, drawn upon the vector cosmology, was applied in the present work to calculate cosmological fluctuations. Moreover, parameters of the model were constrained and compared using the latest observational data such as Planck and WMAP9.
