Recent developments in warm inflation

V Kamali, M Motaharfar, RO Ramos - Universe, 2023 - mdpi.com
Warm inflation, its different particle physics model implementations, and the implications of
dissipative particle production for its cosmology are reviewed. First, we briefly present the …

The warm inflation story

A Berera - Universe, 2023 - mdpi.com
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 …

Warm inflation and its microphysical basis

A Berera, IG Moss, RO Ramos - Reports on Progress in Physics, 2009 - iopscience.iop.org
The microscopic quantum field theory origins of warm inflation dynamics are reviewed. The
warm inflation scenario is first described along with its results, predictions and comparison …

Scalar perturbation spectra from warm inflation

LMH Hall, IG Moss, A Berera - Physical Review D, 2004 - APS
We present a numerical integration of the cosmological scalar perturbation equations in
warm inflation. The initial conditions are provided by a discussion of the thermal fluctuations …

Warm inflation in the adiabatic regime—a model, an existence proof for inflationary dynamics in quantum field theory

A Berera - Nuclear Physics B, 2000 - Elsevier
Warm inflation is examined in a multi-field model. Solutions are obtained for expansion e-
folds and scalar density perturbations. Nonequilibrium dynamics is restricted to a regime that …

Strong dissipative behavior in quantum field theory

A Berera, M Gleiser, RO Ramos - Physical Review D, 1998 - APS
We study the conditions under which an overdamped regime can be attained in the dynamic
evolution of a quantum field configuration. Using a real-time formulation of finite temperature …

Interactions in scalar field cosmology

AP Billyard, AA Coley - Physical Review D, 2000 - APS
We investigate spatially flat isotropic cosmological models which contain a scalar field with
an exponential potential and a perfect fluid with a linear equation of state. We include an …

Power spectrum for inflation models with quantum and thermal noises

RO Ramos, LA Da Silva - Journal of Cosmology and Astroparticle …, 2013 - iopscience.iop.org
We determine the power spectrum for inflation models covering all regimes from cold
(isentropic) to warm (nonisentropic) inflation. We work in the context of the stochastic …

Warm inflation model building

M Bastero-Gil, A Berera - International Journal of Modern Physics A, 2009 - World Scientific
We review the main aspects of the warm inflation scenario, focusing on the inflationary
dynamics and the predictions related to the primordial spectrum of perturbations, to be …
