Descripción

In warm inflation, substantial radiation production can occur concurrently with the inflationary expansion. In the strong dissipative regime, the temperature dependent dissipative coefficient leads to the wrong spectral index. An imperfect radiation fluid, via shear effects, can successfully solve that problem, although one needs to resort to weakly interacting fluids. However, certain modified gravity models mimic shear effects. This encourages us to consider an f(phi,R) theory in warm inflation, and study its effects on the power spectrum of primordial perturbations.
