摘要

在本文中,我们研究了标量场和查普里金模型存在时的膨胀参数和沼泽地猜想。我们研究了存在标量场和查普里金气体模型时的膨胀参数,如慢滚参数、标量功率谱、张量功率谱、谱指数和张量与标量之比。我们还讨论了最近提出的沼泽地猜想。我们认为通胀膨胀是由标准标量场驱动的,其衰变比$\Gamma$与标量场$\phi$呈一般幂律关系,热浴温度$T$由$\Gamma(\phi,T)= C_{\phi}给出。\其中 $C_{\phi}$ 是一个无量纲参数,$a$ 是膨胀衰减率。假定我们的模型在强耗散机制$(R\gg1)$下弯曲,我们研究了背景和微扰动力学,得到了最相关的膨胀观测值,如标量功率谱$\mathcal{P_{R}}$、标量谱指数$n_{s}$、耗散比 $R$、张量与标量比 $r$、标量谱指数的运行 $\frac{dn_{s}}{d\ln{k}}$ 和三种不同电位的沼泽地去西特猜想的广义比 $\frac{acute{T}V}{\acute{V}T}$ 。

Chaplygin Gas Inspired Warm Inflation and Swampland Conjecture Through Various Scalar Potentials
In this paper, we investigate the inflationary parameters and swampland conjectures in the presence of scalar field and Chaplygin models. We examine the inflationary parameters, such as slow-roll parameters, the scalar power spectrum, tensor power spectrum, spectral index and the tensor to scalar ratio in the presence of scalar field and Chaplygin gas models. We also discuss the recently proposed swampland conjectures. We consider that the inflationary expansion is driven by a standard scalar field with a decay ratio $\Gamma$ that has a generic power law dependence on the scalar field $\phi$ and the temperature of the thermal bath $T$ is given by $\Gamma(\phi,T)= C_{\phi} \frac{T^{a}}{\phi^{a-1}}$, where $C_{\phi}$ is a dimensionless parameter and $a$ is the inflation decay rate. Assuming that our model bends in a strong dissipative regime $(R\gg1)$, we study the background and perturbative dynamics and obtain the most relevant inflationary observables, such as the scalar power spectrum $\mathcal{P_{R}}$, scalar spectral index $n_{s}$, dissipative ratio $R$, the tensor-to-scalar ratio $r$, running of the scalar spectral index $\frac{dn_{s}}{d\ln{k}}$ and the generalized ratio of the Swampland de-Sitter conjecture $\frac{\acute{T}V}{\acute{V}T}$ for three different potentials.
