论文摘要
我们研究了爱因斯坦 - 高斯邦纳特（EGB）重力框架中两个理论上最有前途的通货膨胀模型，即自然通货膨胀和突变的山顶通货膨胀。在这项工作中，我们尝试在EGB框架中探索这些模型，并将观测值从重力波的速度上限制在$ GW170817 $等于光速。这直接含义与该动作中高斯 - 骨网的非最低耦合。因此，有效潜力获得了新功能。我们不仅分析了通货膨胀动力学，还分析了重新加热动力学以及重力波的相应能量谱。
We study two of the most theoretically promising models of inflation, namely the Natural inflation and the Mutated Hilltop inflation, in the Einstein-Gauss Bonnet(EGB) gravity framework. In this work, we try to explore these models in EGB framework, keeping the observations from $GW170817$ on the speed of gravitational wave to be equal to the speed of light. This has direct implication on the non-minimal coupling to the Gauss-Bonnet invariant in the action. Thus, the effective potential gets new features. We have not only analysed the inflationary dynamics, but also the reheating dynamics and finally the corresponding energy spectrum of the gravitational wave.
