Cylindrical Thin-shell Wormholes in $f(R)$ gravity

Abstract

In this paper, we employ cut and paste scheme to construct thin-shell wormhole of a charged black string with $f(R)$ terms. We consider $f(R)$ model as an exotic matter source at wormhole throat. The stability of the respective solutions are analyzed under radial perturbations in the context of $R+\delta R^2$ model. It is concluded that both stable as well as unstable solutions do exist for different values of $\delta$. In the limit $\delta \to 0$, all our results reduce to general relativity.
