Query: Enhancement of quantum dot peak-spacing fluctuations in the fractional q
  uantum Hall regime   The fluctuations in the spacing of the tunneling resonances through a quantum
dot have been studied in the quantum Hall regime. Using the fact that the
ground-state of the system is described very well by the Laughlin wavefunction,
we were able to determine accurately, via classical Monte Carlo calculations,
the amplitude and distribution of the peak-spacing fluctuations.
  Our results clearly demonstrate a big enhancement of the fluctuations as the
importance of the electronic correlations increases, namely as the density
decreases and filling factor becomes smaller.
  We also find that the distribution of the fluctuations approaches a Gaussian
with increasing density of random potentials.
