Abstract
The formation and dissolution of light and heavy clusters in warm and dilute strongly interacting matter is studied using a generalized relativistic density functional. This phenomenological theoretical description is an extension of a relativistic mean-field model with density dependent nucleons-meson couplings. It considers nuclei as explicit degrees of freedom in addition to nucleons. Nuclei and nucleons are treated as quasiparticles with medium dependent masses. For clusters, one contribution to the mass shift represents an effective way to take into account the Pauli exclusion principle for nucleons, whether free or bound in nuclei. This mechanism causes the dissolution of clusters at high densities. The consequences are explored for compact star matter as an example for the application of the model in astrophysics. General features and open questions of the approach are discussed.
