Wormhole solutions in $f(Q,T)$ gravity with a radial dependent B parameter

Abstract

A possible astrophysical object to be found in General Relativity is the wormhole. This special solution describes a topological bridge connecting points in two distinguished universes or two different points in the same universe. Despite it was never observed so far, is desired to find traversable wormholes, i.e. wormholes which have a throat at which there is no horizon. However, the traversable wormhole constraints yield solutions that violate all the energy conditions in General Relativity. In the last few years, several models to describe gravity beyond $\Lambda$CDM have been proposed. Then, it is relevant to look for wormhole solutions for these new theories. In this study, we are going to unveil new wormhole solutions for the so-called $f(Q,T)$ gravity. This theory of gravity is based on the non-metricity scalar $Q$, which is responsible for the gravitational interaction together with the energy-momentum trace $T$. We use the embedding procedure to find both the energy and the equilibrium conditions for the existence of wormholes. Then, the nontrivial contributions coming from $f(Q,T)$ gravity are embedded into the effective equations for density and pressures. We also considered the presence of exotic strange matter in the wormhole throat. Such a matter obeys the notorious MIT bag Model. We are going to present new scenarios confirming the viability of traversable wormholes in $f(Q,T)$ gravity with the strange matter, satisfying SEC and WEC energy conditions.
