摘要
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 0 and that the temperature of the thermal bath T is given by Γ(φ,T)=CφTa/φa-1,where Cφ is a dimensionless parameter and a is the inflation decay rate.In a scenario where our model operates within a robust dissipative environment(R>>1),we analyze both fundamental and perturbative dynamics to extract key inflationary parameters.These include the scalar power spectrum PR,dissipative ratio R,scalar spectral index ns,tensor-to-scalar ratio r,running of the scalar spectral index dns/dlnk,and generalized ratio of the swampland de-Sitter conjecture T'V/V'T for three different potentials.
