Abstract
The dissolution of clusters in strongly interacting matter with increasing density and temperature can be modeled with different approaches, in particular a geometric excluded-volume mechanism or a more microscopic model with medium dependent mass shift. The predictions of the chemical composition and of thermodynamic properties are compared for two such equation-of-state models that realize these approaches but use the same model for the interaction of nucleons, i.e., a relativistic mean-field model with density-dependent nucleon-meson couplings. The main differences are found for heavy nuclei in the chemical composition of neutron star matter, but the thermodynamic properties of the two models are quite similar.
