Defect formation from defect--anti-defect annihilations [PDF]
Muneto NittaWe show that when a topological defect with extended world-volume annihilates with an anti-defect, there arise topological defects with dimensions less than those of the original defects by one. Domain wall annihilations create vortices while monopole-string annihilations result in instantons. We find that twisted domain wall rings are vortices, whereas twisted monopole rings are instantons.View original: http://arxiv.org/abs/1205.2442
