From inflation to hot big bang -- a tutorial on cosmological perturbations
Mikko Laine, Simona Procacci
These lecture notes are meant as a pedagogic guide to cosmological inflation and the early epochs thereafter. Inflation explains how the seeds for density perturbations, which evol…
Classical equipartition dynamics between axions and non-Abelian gauge fields
Kim V. Berghaus, Adrien Florio, M. Laine +1
Motivated by axion-like inflation and its warm embedding within the Standard Model, we study the early stages of the energy transfer between an axion condensate and an SU(2) gauge…
Evolution of coupled scalar perturbations through smooth reheating. II. Thermal fluctuation regime
M. Laine, S. Procacci, A. Rogelj
Curvature perturbations with short wavelengths exit the Hubble horizon when the universe may contain a thermal plasma in addition to an inflaton field that drives its expansion. We…
Entropy production at electroweak bubble walls from scalar field fluctuations
M. Eriksson, M. Laine
The real-time dynamics of an electroweak phase transition involves large time and distance scales, the domain of hydrodynamics. However, the matching conditions of ideal hydrodynam…
Evolution of coupled scalar perturbations through smooth reheating. I. Dissipative regime
M. Laine, S. Procacci, A. Rogelj
If the inflaton is a heavy scalar field, it may equilibrate slower than some other degrees of freedom, e.g. non-Abelian gauge bosons. In this case, perturbations in the inflaton fi…
Non-relativistic susceptibility and a dark matter application
S. Biondini, Seyong Kim, M. Laine
When thermal rate equations are derived for the evolution of slow variables, it is often practical to parametrize the right-hand side with chemical potentials. To close the system,…
