Description

Understanding many-body correlations in sub-saturated nuclear matter is essential for constructing a reliable equation of state (EOS), with wide-ranging implications in both nuclear and astrophysical contexts. At low densities, bound states of nucleons naturally emerge as a result of these correlations and are often treated phenomenologically within energy density functional (EDF) frameworks by introducing clusters as explicit degrees of freedom (DOF).

Recent EDF-based models have been extended to incorporate effective cluster DOF embedded in dense nuclear matter, informed by experimental evidence for nucleon-nucleon short-range correlations at higher densities. These developments allow for a unified treatment of correlated structures across a wide density range.

In this talk, we present new approaches to include light cluster DOF and their in-medium modifications at sub-saturation densities, within an upgraded time-dependent EDF framework. This enables the modeling of non-equilibrium processes relevant to heavy-ion collisions, particularly the formation of light nuclei and intermediate-mass fragments.

Our unified theoretical framework supports a more complete and consistent description of nuclear matter, bridging equilibrium and dynamical scenarios. By coupling these models to advanced transport simulations and Bayesian inference techniques, we aim to constrain the nuclear EOS using inputs from nuclear structure, reaction experiments, and astrophysical observations—including those related to compact stars and gravitational wave signals from binary mergers.
