AbstractWe consider the influence of an external periodic potential on the fractional quantum Hall effect of two-dimensional interacting electron systems. For many electrons on a torus, we find that the splitting of incompressible ground state degeneracies by a weak external potential diminishes as $exp ( - L/ xi)$ at large system size $L$. We present numerical results consistent with a scenario in which $xi$ diverges at continuous phase transitions from fractional to integer quantum Hall states which occur with increasing external potential strength.
