The 1998 Nobel Prize in Physics was awarded to Robert Laughlin, Horst Störmer, and Daniel Tsui "for their discovery of a new form of quantum fluid with fractionally charged excitations" However, Laughlin's explanation was a phenomenological guess and only applies to fillings $${\displaystyle \nu =1/m}$$ where $${\displaystyle m}$$ is an odd integer. The Coulomb energy of this trial state is significantly higher than the energy of polarized states at this filling fraction.
