Comments on “Coexistence of Composite-Bosons and Composite-Fermions in Quantum Hall Bilayers, Simon et al cond-mat/0301203”

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 the CF state can not become a boson. Simon et al suggest that the total number of CFs and CBs 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 these results are not in agreement with the experimental data.
