Abstract
In this paper, we analyze inflationary parameters and swampland conjectures in the presence of a scalar field and Chaplygin models. We examine inflationary parameters, such as slow-roll parameters, scalar and tensor power spectra, spectral index, and tensor-to-scalar ratio, in the presence of a scalar field and Chaplygin gas models. We also discuss recently proposed swampland conjectures. We assume that the inflationary expansion is driven by a standard scalar field with a decay ratio Γ that has a generic power-law dependence on the scalar field ϕ and that the temperature of the thermal bath T is given by
, where
is a dimensionless parameter and a is the inflation decay rate. In a scenario where our model operates within a robust dissipative environment
, we analyze both fundamental and perturbative dynamics to extract key inflationary parameters. These include the scalar power spectrum
, dissipative ratio R, scalar spectral index
, tensor-to-scalar ratio r, running of the scalar spectral index
, and generalized ratio of the swampland de-Sitter conjecture
for three different potentials.
