Wormhole solutions with a complex ghost scalar field and their instability
arXiv:1710.01884 · doi:10.1103/PhysRevD.97.024002
Abstract
We study compact configurations with a nontrivial wormholelike spacetime topology supported by a complex ghost scalar field with a quartic self-interaction. For this case, we obtain regular asymptotically flat equilibrium solutions possessing reflection symmetry. We then show their instability with respect to linear radial perturbations.
