Warm Inflation with a General Form of the Dissipative Coefficient

Understand

We propose and investigate a general form of the dissipative coefficient $\Gamma=C_{\phi}T^{m}/\phi^{m-1}$ in warm inflation.

• We focus on discussing the strong dissipative processes $r=\Gamma/3H\gg1$ 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.
