The phenomenon of flux pinning is well documented in popular science. It essentially arises from the fact that a superconductor expels all magnetic fields unless the field travels through a very small "quantized" path of defects (called a quantized flux tube and is an example of a quantum vortex). And deforming these paths is energetically very expensive, they represent a local energy minima of sorts.
I'm curious if a dual effect exists for a superinsulator whereby the superinsulator can be pinned in space above a sufficiently strongly charged electric dipole (or monopole+higher pole?). In essence I'm asking a specific version of the question "how far does the phrase: 'superinsulation can be regarded as an exact dual to superconductivity', really go?".
In order for this to exist there needs to be a notion of "charge tube", a notion of quantized charge vortices in a superinsulator.
