Reassessing constant-roll warm inflation [PDF]

Physical Review D
Departing from standard slow-roll conditions is one way of putting the inflationary paradigm to test, and constraining the dynamics of the inflaton field with a constant-rate of roll of the inflaton field, a.k.a. the constant-roll scenario, is one way of

Thermal gravitons from warm inflation

Physical Review D
In warm inflation (WI), the persistent thermal bath that is sustained by dissipative interactions with the inflaton field produces a stochastic background of gravitational waves (GWs).

Warm Inflation with Nonminimal Derivative Coupling [PDF]

Advances in High Energy Physics, 2014
We study the effects of the nonminimal derivative coupling on the dissipative dynamics of the warm inflation where the scalar field is nonminimally coupled to gravity via its kinetic term.

Primordial non-Gaussianity in noncanonical warm inflation with nonminimal derivative coupling

European Physical Journal C: Particles and Fields
In this paper, the scenario of noncanonical warm inflation with nonminimal derivative coupling is introduced, and its primordial non-Gaussianity of perturbations on uniform energy density hypersurfaces is systematically analyzed.

Perturbation Spectra of Warm Inflation in f(Q, T) Gravity [PDF]

The Astrophysical Journal
We investigate the warm inflationary scenario within the context of the linear version of f ( Q , T ) gravity, coupled with both the inflaton scalar field and the radiation field, under the conditions of the strong dissipation regime. First, we calculate

Warm DBI Inflation

, 2010
We propose a warm inflationary model in the context of relativistic D-brane inflation in a warped throat, which has Dirac-Born-Infeld (DBI) kinetic term and is coupled to radiation through a dissipation term. The perturbation freezes at the sound horizon and the power spectrum is determined by a combination of the dissipative parameter and the sound ...

Constant-roll warm inflation within Rastall gravity

Nuclear Physics B
This research paper used a newly proposed strategy for finding the exact inflationary solutions to the Friedman equations in the context of Rastall theory of gravity (RTG), which is known as constant-roll warm inflation (CRWI).
