Abstract:  Correlations can be regarded as the effects felt by the single-nucleon propagation due to the surrounding nuclear medium. Their impact varies according to the phenomena considered and the region of the nuclear chart under investigation. With the aim of comparing different many-body approaches, three applications will be discussed: novel phenomenological interactions introduced as the generators of Nuclear Energy Density Functional. Deuteron-induced transfer reactions described in an ab initio framework, the No-Core Shell Model combined with the Resonating Group Method. The electromagnetic response of medium-mass nuclei in the Self Consistent Green\'s Function formalism, with a special focus on the role of the two-nucleon propagator in describing both excited states of nuclei up to the drip lines and processes mediated by two-body currents.
