Random interactions are used to investigate to what extent the low-lying behavior of even-even nuclei depend on particular nucleon-nucleon interactions. The surprising results that were obtained for the interacting boson model, i.e. the dominance of ground states with L = 0 and the occurrence of both vibrational and rotational structure, are interpreted and explained in terms of a mean-field an...

The positivity conditions of the spin density matrix constrain the spin observables of the reaction p̄p → ΛΛ, leading to model-independent, non-trivial inequalities. The formalism is briefly presented and examples of inequalities are provided.

Several pairing schemes currently used to describe superfluid nuclei through Hartree-Fock-Bogolyubov (HFB) calculations are briefly reviewed. We put a particular emphasis on the regularization recipes used in connection with zero-range forces and on the density dependence which usually complement their definition. Regarding the chosen regularization process, the goal is not only to identify the...
