Warm natural inflation is studied for the case of the original cosine potential. The radiation
bath during inflation induces a dissipation (friction) rate in the equation of motion for the …

We revisit the framework of axion-like inflation in view of the possibility that the coupling of
the inflaton to a non-Abelian topological charge density could lead to the generation of a …

A bstract We study the impact of sphaleron-induced thermal friction on the axion dark-matter
abundance due to the interaction of an axion-like particle (ALP) with a dark non-abelian …

A bstract After motivating an interest in the shape of the topological charge density spectral
function in hot Yang-Mills theories, we estimate it with the help of thermally averaged …

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

Supergravity, a locally supersymmetric gauge theory, may provide to describe new physics
beyond the Standard Model (BSM), such as slow-roll inflation, the cosmological constant …
