In contrast, in most observed fractions (e.g., Jain sequence), a non-quantized plateau as a function of temperature is impossible. These findings agree with the experimental results, which show a plateau for the ν=2/3 and integer states but not for ν=1/3 and ν=2/5 states. In addition, we find an intermediate phase in which PZMs are not present, but the conductance is similar to the gapped phase, implying that CAR rates are not a definitive indication of PZMs' presence.
