Creating Vortons and Knot Solitons via Domain Wall Pair Annihilation in BEC and Field Theory

Nitta, M (Keio University)
Friday 07 December 2012, 11:20-11:40

Seminar Room 1, Newton Institute


We show that when a vortex-string is stretched between a pair of a domain wall and an anti-domain wall in two component Bose-Einstein condensates, there remains a vorton after the pair annihilation. We also show that the same configuration in the mass deformed Faddeev-Skyrme model results in a knot soliton (Hopfion) after the pair annihilation.
