Spherically symmetric wormholes in minimally coupled f(R,T) gravity

Abstract

In this manuscript, we construct a spherical thin shell wormhole in the background of the minimally coupled f(R, T) model. In this gravitational theory, f is an arbitrary functional form that depends on the Ricci scalar (R) as well as the trace of stress-energy tensor (T). To continue our systematic analysis, we use a cut and paste approach to link two surfaces, i.e., interior and exterior. We find energy-momentum density along with surface pressure for f(R, T) gravitational f(R, T) = R + α R 2 + λ T model, by using the Lanczos equation. We utilize the polytropic equation of state to check the dynamical behavior of the wormhole. A standard potential approach is applied to check the stability of constructed wormhole with throat radius a 0. Graphical analysis shows that the stability regions of wormholes rely on the specific values mass M to charge Q ratio.
