Abstract
The zeros of complex Gaussian random polynomials, with coefficients such th at the density in the underlying complex space is uniform, are known to hav e the same statistical properties as the zeros of the coherent state repres entation of one-dimensional chaotic quantum systems. We extend the interpre tation of these polynomials by showing that they also arise as the wavefunc tion for a quantum particle in a magnetic field constructed from a random s uperposition of states in the lowest Landau level. A study of the statistic al properties of the zeros is undertaken using exact formulae for the one- and two-point distribution functions. Attention is focused on the moments o f the two-point correlation in the bulk, the variance of a linear statistic , and the asymptotic form of the two-point correlation at the boundary. A c omparison is made with the same quantities for the eigenvalues of complex G aussian random matrices.
