To understand how this untying works, we simulate the behavior of 1,458 superfluid vortex knots of varying complexity and scale in the Gross-Pitaevskii equation. Without exception, we find that the knots untie efficiently and completely, and do so within a predictable time range. We also ...
How superfluid vortex knots untie Abstract Knots and links often occur in physical systems, including shaken strands of rope1and DNA (ref.2), as well as the more subtle structure of vortices in fluids3and magnetic fields in plasmas4. Theories of fluid flows without dissipation predict these tan...
