Abstract
This chapter is devoted to applications of EGOE(1+2) and EGOE(1+2)-s to nuclei and mesoscopic systems. For example, simple applications to quantum dots and small metallic grains include: (i) delay in Stoner instability due to random interactions; (ii) odd-even staggering in ground state energies; (iii) distribution of conductance peak spacings. Similarly, the spin dependent chaos markers provide a stronger basis for statistical nuclear spectroscopy and presented in this topic are: (i) theory for smoothed level densities and occupancies in nuclei with interactions; (ii) simple form for transition strengths generated by one-body transition operators; (iii) binary correlation results showing that the transition strength density, for operators like those that generate neutrinoless double beta decay transition matrix elements, will take bivariate Gaussian form.
