Density fluctuations from warm inflation

, 2009
Thermal fluctuations provide the main source of large scale density perturbations in warm inflationary models of the early universe. For the first time, general results are obtained for the power spectrum in the case when the friction coefficient in the ...

Non-Minimal Warm Inflation and Perturbations on the Warped DGP Brane with Modified Induced Gravity

, 2010
We construct a warm inflation model with inflaton field non-minimally coupled to induced gravity on a warped DGP brane. We incorporate possible modification of the induced gravity on the brane in the spirit of $f(R)$-gravity.

Constraining chameleon field driven warm inflation with Planck 2018 data

European Physical Journal C: Particles and Fields, 2019
We investigate warm inflationary scenario in which the accelerated expansion of the early Universe is driven by chameleon-like scalar fields. Due to the non-minimal coupling between the scalar field and the matter sector, the energy-momentum tensor of ...

Adiabatic out-of-equilibrium solutions to the Boltzmann equation in warm inflation

Journal of High Energy Physics, 2018
We show that, in warm inflation, the nearly constant Hubble rate and temperature lead to an adiabatic evolution of the number density of particles interacting with the thermal bath, even if thermal equilibrium cannot be maintained.

Warm deformed Inflation

Nuclear Physics, 2023
In this work, we study warm inflationary scenario based on a deformation of R2 gravity. We start considering Rp and assume p=2(1+δ) with δ≪1 so that we simply obtain warm R2 inflation when setting δ=0. We then derive the potential in the Einstein frame and consider a dissipation parameter of the form Γ=C1T with C1 being a coupling parameter.

Dynamics of polynomial Chaplygin gas warm inflation

European Physical Journal C: Particles and Fields, 2017
In the present work, we study the consequences of a recently proposed polynomial inflationary potential in the context of the generalized, modified, and generalized cosmic Chaplygin gas models. In addition, we consider dissipative effects by coupling the

Warm multi-natural inflation

Journal of Cosmology and Astroparticle Physics
Abstract Multi-natural inflation is studied in the context of warm inflation. We study the warm multi-natural inflation scenario with both linear and cubic temperature-dependent dissipation coefficients. The model is motivated by axion-like inflation models with coupling to non-Abelian gauge fields through a dimension-five ...
