Static spherically symmetric wormholes in generalized $f (R, ϕ)$ gravity

M. Zubair, Farzana Kousar, Sebastian Bahamonde

In this paper, we examine static spherically symmetric wormhole solutions in generalized $f (R, ϕ)$ gravity. To do this, we consider three different kinds of fluids: anisotropic, bar…

Reconstruction of Scalar Potentials in $f (R, R_{α β} R^{α β}, ϕ)$ theory of gravity

M. Zubair, Farzana Kousar, Saira Waheed

In this paper, we explore the nature of scalar field potential in $f (R, R_{α β} R^{α β}, ϕ)$ gravity using a well-motivated reconstruction scheme for flat FRW geometry. The beauty of…

Cosmological reconstruction and energy bounds in $f (R, R_{α β} R^{α β}, ϕ)$ gravity

M. Zubair, Farzana Kousar

We discuss the cosmological reconstruction of $f (R, R_{α β} R^{α β}, ϕ)$ (where $R$ , $R_{α β} R^{α β}$ and $ϕ$ represents the Ricci scalar, Ricci invariant and scalar field) corresponding…

Thermodynamics in $f (R, R_{α β} R^{α β}, ϕ)$ theory of gravity

M. Zubair, Farzana Kousar, Sebastian Bahamonde

First and second laws of black hole thermodynamics are examined at the apparent horizon of FRW spacetime in $f (R, R_{α β} R^{α β}, ϕ)$ gravity, where $R$ , $R_{α β} R^{α β}$ and $ϕ$ are th…
