Ok, I asked a professional physicist and he told me:
> Fractional charges and fractional quantum hall effect are related. The

> whereby the charge carriers were transported across a microscopic
> constriction. As one increases the potential difference across the
> constriction, one sees a fractional increase in the current
> corresponding to a multiple charge of e/3.

> This observation doesn't mean that the fundamental charge is anything
> less than e, or that the fundamental value of h is h/3. The fractional
> quantities observed here is due to many-body effects. The collective
> interactions of ALL the charges under reduced dimensions (2D instead
> of the typical 3D) together conspire to produce this emergent
> phenomena.
