This thesis is dedicated to discuss the inflationary setup with the help of modified Barrow
entropy with f (R) gravity framework. We derive the Friedmann equations by using the
first law of thermodynamics. With the help of these equations, we reconstruct f (R) gravity
model to establish the relationships governing scalar and tensor perturbation power spectra
and interestingly this model mimics thermodynamically under the slow-roll approximation.
Two different types of potentials like the β potential and the exponential potential are used
to explore the insights of inflationary parameters in the underlying scenario. Thus, the
inflation-related quantities like scalar spectral index and tensor-to-scalar ratio are discussed
graphically in our scenario by developing contour plots. It is worthwhile mention here that
our results are consistent with Planck 2018 data. |
