Phys. Rev. Lett. 73, 2119–2122 (1994)Off-Diagonal Long Range Order and Scaling in a Disordered Quantum Hall SystemReceived 8 February 1994; published in the issue dated 10 October 1994 We have numerically studied bosonic off-diagonal long range order, introduced by Read to describe the ordering in ideal quantum Hall states, for noninteracting electrons in random potentials confined to the lowest Landau level. We find that it also describes the ordering in disordered quantum Hall states; the proposed order parameter vanishes in the disordered (σxy=0) phase and increases continuously from zero in the ordered (σxy=e2/h) phase. We study the scaling of the order parameter and find that it is consistent with that of the one-electron Green function. © 1994 The American Physical Society URL:
