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 …

Primordial gravitational waves from NANOGrav: A broken power-law approach

M Benetti, LL Graef, S Vagnozzi - Physical Review D, 2022 - APS
We revisit the possibility that the stochastic common-spectrum process recently detected by
the NANOGrav pulsar timing array experiment could be due to primordial gravitational …

Trans-Planckian censorship and inflationary cosmology

A Bedroya, R Brandenberger, M Loverde, C Vafa - Physical Review D, 2020 - APS
We study the implications of the recently proposed Trans-Planckian censorship conjecture
(TCC) for early Universe cosmology and in particular inflationary cosmology. The TCC leads …

Warm Inflation in the light of Swampland Criteria

S Das - Physical Review D, 2019 - APS
Warm inflation seems to be the most befitting single-field slow-roll inflation scenario in the
context of the recently proposed swampland criteria. We investigate the constraints these …

Observational constraints on warm natural inflation

G Montefalcone, V Aragam, L Visinelli… - Journal of Cosmology …, 2023 - iopscience.iop.org
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 …

WarmSPy: a numerical study of cosmological perturbations in warm inflation

G Montefalcone, V Aragam, L Visinelli… - Journal of Cosmology …, 2024 - iopscience.iop.org
We present WarmSPy, a numerical code in Python designed to solve for the perturbations'
equations in warm inflation models and compute the corresponding scalar power spectrum …

[LIVRE][B] Noether symmetries in theories of gravity

F Bajardi, S Capozziello - 2022 - books.google.com
This volume summarizes the many alternatives and extensions to Einstein's General Theory
of Relativity, and shows how symmetry principles can be applied to identify physically viable …

Note on single-field inflation and the swampland criteria

S Das - Physical Review D, 2019 - APS
The recently proposed swampland criteria aim to evade any (meta-) stable de Sitter
constructions within string landscapes, making it difficult to accommodate accelerating …

Warm brane inflation with an exponential potential: a consistent realization away from the swampland

V Kamali, M Motaharfar, RO Ramos - Physical Review D, 2020 - APS
It has very recently been realized that coupling branes to higher dimensional quantum
gravity theories and considering the consistency of what lives on the branes, one is able to …
