Traversable Wormholes in $R + α R^{n}$ Gravity

Nisha Godani, Gauranga C. Samanta

In this work, the study of traversable wormholes in $f (R)$ gravity with the function $f (R) = R + α R^{n}$ , where $α$ and $n$ are arbitrary constants, is taken into account. The shape func…

Physical Parameters for Stable $f (R)$ Models

Gauranga C Samanta, Nisha Godani

Nojiri \& Odintsov \cite{noj1} and Hu \& Sawicki \cite{hu} have studied non-linear functions in modified gravity that explain the cosmic acceleration without cosmological constant,…

Validation of Energy Conditions in Wormhole Geometry within Viable $f (R)$ Gravity

Gauranga C Samanta, Nisha Godani

In this work, wormholes, tunnel like structures introduced by Morris \& Thorne \cite{Morris95}, are explored within the framework of $f (R)$ gravity. Using the shape function $b(r)=…

Wormhole Modeling Supported by Non-Exotic Matter

Gauranga C. Samanta, Nisha Godani

In the present paper, the modelling of traversale wormholes, proposed by Morris \& Thorne \cite{morris1}, is performed within the $f (R)$ gravity with particular viable case $f(R)=R…

Non violation of energy conditions in wormholes modelling

Nisha Godani, Gauranga C. Samanta

Morris \& Thorne \cite{morris1} proposed geometrical objects called traversable wormholes that act as bridges in connecting two spacetimes or two different points of the same space…
