Query: Parametric invariant Random Matrix Model and the emergence of
  multifractality   We propose a random matrix modeling for the parametric evolution of
eigenstates. The model is inspired by a large class of quantized chaotic
systems. Its unique feature is having parametric invariance while still
possessing the non-perturbative crossover that has been discussed by Wigner 50
years ago. Of particular interest is the emergence of an additional crossover
to multifractality.
