It has been known there is fractional quantum number induced in a soliton profile, such as this Jeffrey Goldstone and Frank Wilczek paper and many works of Jackiw.
For example the electric charge trapped at the soliton can have charge 1/2 e.
Q: Are there experiments capturing this fractional quantum number induced in a soliton profile? What are they? (Ref are fine. But please be wisely chosen for experiments articles.)
such as in Polyacetylene, or like graphene device?
