Recent developments in many-body quantum chaos have raised the
issue of correlations between different families of levels in the
spectra of random fermionic systems. It seems that rotational
invariance is sufficient to force an otherwise random system to have
statistically ordered spectra where the ground state can have the
maximum spin allowed or zero spin a huge portion of the time. We
have tackled this question and have characterized the role of
``geometric chaoticity'' and pairing in random systems. We have shown
how the geometry gives rise to such a distribution of ground state
spins and examined the coexistence of these regularities with chaotic
wave functions.
