The Approach to Vortex Reconnection
- 117 Downloads
We present numerical solutions of the Gross–Pitaevskii equation corresponding to reconnecting vortex lines. We determine the separation of vortices as a function of time during the approach to reconnection, and study the formation of pyramidal vortex structures. Results are compared with analytical work and numerical studies based on the vortex filament method.
