Probing the existence of the ZTF Casimir wormholes in the framework of $f(\mathcal{R})$ gravity

Oleksii Sokoliuk, Alexander Baransky, P. K. Sahoo

For the spherically symmetric static traversable wormholes, supported by the Casimir energy in $f(\mathcal{R})=\mathcal{R}+\alpha {\mathcal{R}}^2$ Quadratic, $f(\mathcal{R})=f_0 \mathcal{R…
