| dc.description | Simon et al suggest that composite fermions (CF) must be replaced by composite bosons (CB) and "111" state is a boson state. However, we find that such a transition in real GaAs is not possible and CF state cannot become a boson. Simon et al suggest that the total number of CF and CB is conserved. However, we find that the number of quasiparticles need not be conserved. Similarly, Simon et al suggest that CFs are formed but we find that this formation does not conserve energy so that CFs will not be formed. Simon et al compute using products of fermion and boson wave functions. We find that the mass of the CF is much too larger than experimental mass. We find that these computed results are not in agreement with the data. | |
