Quantum symmetrical statistical system: Ginibre-Girko ensemble

统计力学 2007-05-23 v2

摘要

The Ginibre ensemble of complex random Hamiltonian matrices HH is considered. Each quantum system described by HH is a dissipative system and the eigenenergies ZiZ_{i} of the Hamiltonian are complex-valued random variables. For generic NN-dimensional Ginibre ensemble analytical formula for distribution of second difference Δ1Zi\Delta^{1} Z_{i} of complex eigenenergies is presented. The distributions of real and imaginary parts of Δ1Zi\Delta^{1} Z_{i} and also of its modulus and phase are provided for NN=3. The results are considered in view of Wigner and Dyson's electrostatic analogy. General law of homogenization of eigenergies for different random matrix ensembles is formulated.
