Fractional quantum Hall ν=1/m: quasihole charge and plasma screening
Laughlin's plasma analogy: |Ψ_m|² maps to a classical 2D one-component plasma at inverse temperature β=2m. Electrons (blue) interact logarithmically; quasiholes (gold) carry fractional charge e/m. The plasma screens quasihole charge: each quasihole creates a depletion "hole" in the electron density, visible as a deficit region.
