Wormholes without exotic matter in Einstein–Cartan theory

We study the possible existence of static traversable wormholes without invoking exotic matter in the framework of the Einstein–Cartan theory. A family of exact static, spherically symmetric wormhole solutions with an arbitrary throat radius, with flat or AdS asymptotic behavior, has been obtained with sources in the form of two noninteracting scalar fields with nonzero potentials. Both scalar fields are canonical (that is, satisfy the weak energy condition), one is minimally and the other nonminimally coupled to gravity, and the latter is a source of torsion. © 2015, Pleiades Publishing, Ltd.
