Level statistics in the quantum Hall regime
  The statistical properties of energy eigenvalues in the critical regime of the lowest Landau band are investigated. The nearest neighbour level spacing distribution $P(s)$ and the Mehta quantity $I_0$, from which the scaling exponent $\nu$ of the correlation length can be derived, are calculated. While $P(s)$ disagrees with recent analytical predictions, $\nu$ is found to be in agreement with theoretical and experimental results.
