Non-metric construction of spacetime defects
Jose M. Queiruga
We describe a spacetime endowed with a non-metricity tensor which effectively serves as a model of a spacetime foam. We explore the consequences of the non-metricity in several $f(…

A stealth defect of spacetime
F. R. Klinkhamer, J. M. Queiruga
We discuss a special type of Skyrmion spacetime-defect solution, which has a positive energy density of the matter fields but a vanishing asymptotic gravitational mass. With a mass…

Antigravity from a spacetime defect
F. R. Klinkhamer, J. M. Queiruga
We argue that there may exist spacetime defects embedded in Minkowski spacetime, which have negative active gravitational mass. One such spacetime defect then repels a test particl…
