SUSY Chern-Simons and baby Skyrme models and their BPS structures
Jose M. Queiruga
We construct the supersymmetric extensions of different models containing a Chern-Simons term and study their BPS structure. We find that the coupling of the Chern-…

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…
