Query: Universal spectral correlations in ensembles of random normal matrices   We consider non-gaussian ensembles of random normal matrices with the
constraint that the ensembles are invariant under unitary transformations. We
show that the level density of eigenvalues exhibits disk to ring transition in
the complex plane. We also show that the n-eigenvalue correlation and the
spacing distribution are universal and identical to that of complex (Gaussian)
Ginibre ensemble. Our results are confirmed by Monte Carlo calculations. We
verify the universality for dissipative quantum kicked rotor system.
