The statistical properties of eigenvalues are investigated by measuring quantities such as the nearest-neighbor level spacing distribution and the Dyson-Metha statistics for two types of ensembles known as orthogonal and unitary, and for three values of the system parameter controlling chaos.Physics Letters, Section A: General, Atomic and Solid State Physics = Physics Letters, Section A: General, Atomic and Solid State Physics 2453-41831881998-08-17Elsevier 03759601 https://doi.org/10.1016/S0375-9601(98)00357-0© 1998 Published by Elsevier B.V.none2013-01-25
