Inflationary Cosmology in a non-minimal gravity theory using a mixing term
Payel Sarkar, Ashmita, Prasanta Kumar Das
We investigate a class of inflationary models in modified gravity theories which contain a non-minimal coupling between gravity and a scalar field (inflaton) as $f(R,T)=R \bigl…
Observational Constraints on the gravity theory
Ashmita, Payel Sarkar, Prasanta Kumar Das
We investigate inflation in modified gravity framework by introducing a direct coupling term between a scalar field and the trace of the energy momentum tensor as $f(ϕ,T) =…
Inflationary Cosmology in the Modified Gravity
Ashmita, Payel Sarkar, Prasanta Kumar Das
In this work, we study the inflationary cosmology in modified gravity theory ( is the modified gravity parameter) with three distinct class of inflation pot…
Emergent Cosmology in Models of Nonlinear Electrodynamics
Payel Sarkar, Prasanta Kumar Das
Nonlinear electrodynamics, which acts as a source of gravity Einstein field equations, leads to emergent cosmology, an alternative solution which can avoid Big Bang singularity. In…
