  abstractNote={<jats:p>We provide a description of even-even <jats:italic>N</jats:italic> = <jats:italic>Z</jats:italic> nuclei in a formalism of quartets. Quartets are four-body correlated structures characterized by isospin <jats:italic>T</jats:italic> and angular momentum <jats:italic>J</jats:italic>. We show that the ground state correlations induced by a realistic shell model interaction can be well accounted for in terms of a restricted set of <jats:italic>T</jats:italic> = 0 low–<jats:italic>J</jats:italic> quartets, the <jats:italic>J</jats:italic> = 0 one playing by far a leading role among them. A conceptually similar description of odd-odd self-conjugate nuclei is given in terms of two distinct families of building blocks, one formed by the same <jats:italic>T</jats:italic> = 0 quartets employed for the even-even systems and the other by collective pairs with either <jats:italic>T</jats:italic> = 0 or <jats:italic>T</jats:italic> = 1. Some applications of this formalism are discussed for nuclei in the <jats:italic>sd</jats:italic> shell.</jats:p>},
