Cosmological structure growth in energy-momentum squared gravity

Alvaro de la Cruz-Dombriz, Peter K. S. Dunsby, Payel Sarkar

We investigate the cosmological evolution of matter perturbations in the modified gravity model $f (R, T^{2})$ , where $T^{2} = T_{μν} T^{μν}$ denotes the quadratic contraction of the energy…

Non-Minimal Inflation with a scalar-curvature mixing term $\frac{1}{2} ξ R ϕ^{2}$

Payel Sarkar, Ashmita, Prasanta Kumar Das

We use the PLANCK 2018 and the WMAP data to constraint inflation models driven by a scalar field $ϕ$ in the presence of the non-minimal scalar-curvature mixing term $\frac{1}{2}ξR…
