Introduced first is the classification of the classical GOE, GUE and GSE ensembles. To get started with their properties, nearest neighbor spacing distributions (NNSD) for the simple 2×2 matrix version of these ensembles are derived. Going further, one and two-point functions (in the eigenvalues) for general N×N GOE and GUE are derived using the so called binary correlation approximation. Measures for level fluctuations as given by the number variance and Dyson-Mehta Δ3 statistic on one hand and on the other strength functions, information entropy and Porter-Thomas distribution for wave function structure as generated by these ensembles are briefly discussed. In addition, presented are some aspects of data analysis. © 2014 Springer International Publishing Switzerland.
