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.
