Constructing Viable Interacting Dark Matter and Dark Energy Models: A Dynamical Systems Approach
Ashmita, Kinjal Banerjee, Prasanta Kumar Das
We study the evolution of FLRW cosmological models for two interacting Dark Matter-Dark Energy Models using dynamical system analysis. Since we are interested in late time e…
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…
Non-Minimal Inflation with a scalar-curvature mixing term
Payel Sarkar, Ashmita, Prasanta Kumar Das
We use the PLANCK 2018 and the WMAP data to constraint inflation models driven by a scalar field in the presence of the non-minimal scalar-curvature mixing term $\frac{1}{2}ξR…
