“…This finding is in agreement with all the theoretical microscopic modelizations which are naturally elaborated inside a single Wigner-Seitz cell within a fixed number of particles [36][37][38][39]. All these canonical studies agree in predicting that matter is clusterized for all subsaturation densities and the cluster size and composition evolve continuously with the density, which is incompatible with a modelization based on phase coexistence [40] where only the relative proportion of the two phases varies through the phase transition.…”

A simple, exactly solvable statistical model is presented for the description of baryonic matter in the thermodynamic conditions associated to the evolution of core-collapsing supernova. It is shown that the model presents a first order phase transition in the grandcanonical ensemble which is not observed in the canonical ensemble. Similar to other model systems studied in condensed matter physics, this ensemble in-equivalence is accompanied by negative susceptibility and discontinuities in the intensive observables conjugated to the order parameter. This peculiar behavior originates from the fact that baryonic matter is subject to attractive short range strong forces as well as repulsive long range electromagnetic interactions, partially screened by a background of electrons. As such, it is expected in any theoretical treatment of nuclear matter in the stellar environement. Consequences for the phenomenology of supernova dynamics are drawn.

“…Recently, more complicated structures with intersecting rods have been predicted by calculations beyond the Wigner-Seitz approximation [51,52,53,54,55,56]. On the other hand, a liquid-drop approach [57,58] can be used for the purpose of examining the possible occurrence of a periodic bicontinuous structure, namely, gyroid, which is known to occur in polymer systems [59].…”

Abstract. Phenomenological approach to inhomogeneous nuclear matter is useful to describe fundamental properties of atomic nuclei and neutron star crusts in terms of the equation of state of uniform nuclear matter. We review a series of researches that we have developed by following this approach. We start with more than 200 equations of state that are consistent with empirical masses and charge radii of stable nuclei and then apply them to describe matter radii and masses of unstable nuclei, proton elastic scattering and total reaction cross sections off unstable nuclei, and nuclei in neutron star crusts including nuclear pasta. We finally discuss the possibility of constraining the density dependence of the symmetry energy from experiments on unstable nuclei and even observations of quasi-periodic oscillations in giant flares of soft gamma-ray repeaters.
