Evolution of a superfluid vortex filament tangle driven by the Gross-Pitaevskii equation
Evolution of a superfluid vortex filament tangle driven by the Gross-Pitaevskii equation
The development and decay of a turbulent vortex tangle driven by the Gross-Pitaevskii equation is studied. Using a recently developed accurate and robust tracking algorithm, all quantized vortices are extracted from the fields. The Vinen's decay law for the total vortex length with a coefficient that is in quantitative agreement …
