耗散系数具有一般形式的热膨胀

Warm Inflation with a General Form of the Dissipative Coefficient

Yi Zhang

摘要:

本文提出并研究了热膨胀中耗散系数$Γ=C_ϕT^{m}/ϕ^{m-1}$的一般形式。重点讨论了近似平衡热态下的强耗散过程$r=Γ/3H\gg1$。对于这个模型,我们给出了慢滚条件、耗散系数一般形式下功率谱的幅值和指数。此外,还对单项势和类混合势进行了具体分析。我们认为$m=0,3$病例尤其值得进一步研究。

英文摘要:

We propose and investigate a general form of the dissipative coefficient $Γ=C_ϕT^{m}/ϕ^{m-1}$ in warm inflation. We focus on discussing the strong dissipative processes $r=Γ/3H\gg1$ 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. We conclude that the $m=0,3$ cases are worthy further investigation especially.
