Observation of Self-Patterned Defect Formation in Atomic Superfluids–from Ring Dark Solitons to Vortex Dipole Necklaces
Hikaru Tamura, Cheng-An Chen, Chen-Lung Hung
Abstract
The interaction between a superfluid and an enclosing circular box generates a ring-shaped dark soliton that evolves into a complex vortex structure, showing a novel way of generating structured topological defects.
