We present an analysis based on the generator coordinate method that allows one to disentangle the neutron and proton contributions to the properties of low-lying collective states in oxygen isotopes.

We propose a variational principle which can be used to extract successively the optimal average value and dispersion associated with the measure of a given operator at a final time t1 on a system whose density matrix is known at some initial time t0

Superconductivity has been discovered almost a century ago. The understanding of the underlying mechanisms took approximately fifty years of efforts and required the input of several outstanding physicists such as London, Landau, Bogoliubov, Abrikoso

Odd-even effects are manifest in many properties of small superconducting systems such as nuclei and nanometric aluminium grains. The BCS equations provide a natural tool to investigate these effects at zero temperature. Here we give and discuss the
