Dynamical evolution and decay of multi-charged quantum vortex in a Bose-Einstein condensate

We report the observation of the twisted decay of quadruply charged vortices taking place in an atomic Bose-Einstein condensate. Supporting numerical simulations show that the singly-charged vortices, which result from the decay of a multi-charged vortex, twist around intertwined in the shape of helical Kelvin waves.

Automated summary

This study reports the observation of twisted decay of quadruply charged vortices in an atomic Bose-Einstein condensate. Numerical simulations confirm that singly-charged vortices resulting from the decay exhibit twisted, helical Kelvin waves.
