    Wormhole solutions in f(T) gravity with noncommutative geometry (2013)
    American Physical Society (APS)
    Details
    Publication Date: 2013-12-03
    Description: Author(s): M. Sharif and Shamaila Rani The objective of this paper is to study static spherically symmetric noncommutative wormhole solutions in the framework of f ( T ) gravity. We construct f ( T ) field equations in covariant and effective energy-momentum tensor forms to make a correspondence with general relativity. It is observed that the... [Phys. Rev.

    Galactic Halo Wormhole Solutions in Gravity (2014)
    Hindawi
    Details
    Publication Date: 2014-11-28
    Description: The proposal of galactic halo region is based on the idea that dark halos contain some characteristics needed to support traversable wormhole solutions. We explore wormhole solutions in this region in the framework of generalized teleparallel gravity. We consider static spherically symmetric wormhole spacetime with flat galactic rotational curves and obtain expressions of matter components for nondiagonal tetrad. The effective energy-momentum tensor leads to the violation of energy conditions which may impose condition on the normal matter to satisfy these conditions. We take two well-known models in exponential and logarithmic forms to discuss wormhole solutions as well as the equilibrium condition. It is concluded that wormhole solutions violating weak energy condition are obtained for both models with stable configuration.
