of the setup.
The disks represent the bosonic condensate
density and the blue balls in the vortex core represent the
fermionic density. The black line is a guide to the eye to see
the wiggling of the vortex line that corresponds to a so-called Kelvin mode, which provides the bosonic part of the superstring (image and text: arXiv.org/abs/cond-mat/0505055).
