Query: Entropy, Maximum Entropy Priciple and quantum statistical information
  for various random matrix ensembles   The random matrix ensembles (RME) of quantum statistical Hamiltonians, e.g.
Gaussian random matrix ensembles (GRME) and Ginibre random matrix ensembles
(Ginibre RME), are applied in literature to following quantum statistical
systems: molecular systems, nuclear systems, disordered materials, random Ising
spin systems, and two-dimensional electron systems (Wigner-Dyson electrostatic
analogy). Measures of quantum chaos and quantum integrability with respect to
eigenergies of quantum systems are defined and calculated. Quantum statistical
information functional is defined as negentropy (opposite of entropy or minus
entropy). Entropy is neginformation (opposite of information or minus
information. The distribution functions for the random matrix ensembles are
derived from the maximum entropy principle.
