Warm Inflation with a General Form of the Dissipative Coefficient

الأصل · EN

We propose and investigate a general form of the dissipative coefficient Γ=CϕTᵐ/ϕᵐ⁻¹ in warm inflation. We focus on discussing the strong dissipative processes r=Γ/3H≫1 in the thermal state of approximate equilibrium. To this toy model, we give the slow-roll conditions, the amplitude and the index of the power spectrum under the general form of dissipative coefficient. Furthermore, the monomial potential and the hybrid-like potential are analyzed specifically. We conclude that the m=0,3 cases are worthy further investigation especially.
