| The random matrix ensembles (RME) of Hamiltonian matrices, e.g. Gaussian random matrix ensembles (GRME) and Ginibre random matrix ensembles (Ginibre RME), are applicable to following quantum statistical systems: nuclear systems, molecular systems, condensed phase systems, disordered systems, and two-dimensional electron systems (Wigner-Dyson electrostatic analogy). A family of quantum anharmonic oscillators is studied and the numerical investigation of their eigenenergies is presented. The statistical properties of the calculated eigenergies are compared with the theoretical predictions inferred from the random matrix theory. Conclusions are derived. |
