The integer quantum Hall effect II
... In the last lecture we have seen that for spinless fermions and for a time-reversal invariant system all states are localized in two spatial dimensions. How can we reconcile this with the above argument for the quantization of xy . The answer is, that for the case of a magnetic field, where time rev ...
