Rotating Traversable wormholes with two cosmic strings at the throat

Abstract: This paper investigates how rotating traversable wormholes incorporate two cosmic strings at the throat of the wormhole. Building on arXiv:gr-qc/9803098v2 for rotating traversable wormholes and arXiv:gr-qc/0401036 analysis of scalar perturbations, a modified metric that accounts for these cosmic string perturbations is presented. This paper evaluates the Null Energy Condition in the presence of these string perturbations and focuses mainly on the scalar field dynamics in this modified spacetime. Using localized Gaussian perturbations to model cosmic string effects, this paper discusses the impact of angular and radial distributions from the cosmic strings on the spacetime geometry. Regularization has been applied to the shape function and energy condition violations at the wormhole throat, helping to eliminate divergences. The paper concludes with the result that the presence of cosmic strings induces unique anisotropic contributions. Future work could explore gravitational wave signatures associated with similar systems.
