The alternative to the incompressible fractional charge in the quantum Hall effect: Comments on Laughlin and Schrieffer's papers
arXiv:cond-mat/0210238
Abstract
Laughlin has found "exactly" the wave function which is ascribed to an excitation of fractional charge, such as e/3. We find that the exactness of the wave function is not destroyed by changing the charge to some other quantity such as the magnetic field. Thus e/3 and H can be replaced by e and H/3. Therefore, the wave function need not belong to quasiparticles of charge e/3.
