چکیده

Abstract We investigate theoretical and observational aspects of a warm inflation scenario driven by the $$\beta $$ β -exponential potential, which generalizes well-known power law inflation. In such scenario, decay inflaton field into radiation happens during inflationary phase. our study, we consider dissipation coefficient ( $$\varGamma Γ ) with cubic dependence on temperature T consequences in dynamics, focusing impact spectral index $$n_s$$ n s , its running $$n_{run}$$ run tensor-to-scalar ratio r . find it possible to realize agreement current cosmic microwave background data weak strong regimes. also model light swampland conjectures, as regime has been known way satisfy three conditions currently discussed literature. that when \propto T^3$$ ∝ T 3 can be accommodated conjectures.

Warm Inflation

Abstract: I show here that there are some interesting differences between the predictions of warm and cold inflation models focusing in particular upon the scalar spectral index ns and the tensor-to-scalar ratio r. The first thing to be noted is that the warm inflation models in general predict a vanishingly small value of r. Cold inflationary models with the potential V = M4 (φ/MP) p and a num...

Extended Warm Inflation

A bidimensional parameter space of unitary area is introduced to study phenomenologically the dynamic and thermodynamic behavior of inflationary models driven by a scalar field coupled to a thermal component. In this enlarged context the isentropic and warm pictures are just extreme cases of an infinite two-parametric family of possible inflationary scenarios. It is also shown that strong coupl...

Thermodynamic approach to warm inflation

We study the thermodynamic behavior of a decaying scalar field coupled to a relativistic simple fluid. It is shown that if the decay products are represented by a thermalized bath, its temperature evolution law requires naturally a new phenomenological coupling term. This “energy loss” term is the product between the enthalpy density of the thermalized bath and the decay width of the scalar fie...

Spontaneous baryogenesis in warm inflation

We discuss spontaneous baryogenesis in the warm inflation scenario. In contrast with standard inflation models, radiation always exists in the warm inflation scenario, and the inflaton must be directly coupled to it. Also, the transition to the post-inflationary radiation dominated phase is smooth and the entropy is not significantly increased at the end of the period of inflation. In addition,...
