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.

The Unitary Correlation Operator Method (UCOM) provides a means for nuclear structure calculations starting from realistic NN potentials. The dominant short-range central and tensor correlations are described explicitly by a unitary transformation. The application of UCOM in the context of the no-core shell model provides insight into the interplay between dominant short-range and residual long...
