In fact, the charge and the magnetic length have not been resolved. It is of serious consequences because fractional charge completely disappears and only the flux area, $ł_o^2$ becomes fractional. The results of Kivelson et al are therefore not unique.5 pages TeXMesoscale and Nanoscale PhysicsNonuniqueness of Kivelson, Kallin, Arovas and Schrieffer' fractional chargetext
