Skyrmion spacetime defect

Abstract

A finite-energy static classical solution is obtained for standard Einstein gravity coupled to an $SO(3)\times SO(3)$ chiral model of scalars [a Skyrme model]. This nonsingular localized solution has nontrivial topology for both the spacetime manifold and the $SO(3)$ matter fields. The solution corresponds to a single spacetime defect embedded in flat Minkowski spacetime.
