Wormhole Geometries In $f(R,T)$ Gravity [PDF]
Tahereh AziziWe study wormhole solutions in the framework of $f(R,T)$ gravity where $R$ is the scalar curvature, and $T$ is the trace of the stress-energy tensor of the matter. We show that in this modified gravity scenario, the matter threading the wormhole may satisfy the energy conditions, so it is the effective stress-energy that is responsible for violation of the null energy condition.View original: http://arxiv.org/abs/1205.6957
