Untying vortex knots in fluids and superfluids

ORAL

Abstract

Recent work has demonstrated that vortex knots appear to always untie in fluids and superfluids. Should we expect the same behavior from these two very different systems? I will discuss this unknotting behavior, both quantitatively -- through helicity -- and qualitatively through the geometry and topology of the vortex lines as they evolve.
