TL;DR

This paper investigates the unstable modes in asymmetric nuclear matter using relativistic mean-field models, comparing their instability characteristics with non-linear Walecka models and discussing distillation effects.

Contribution

It introduces an analysis of density-dependent hadronic models' instabilities and compares them with traditional non-linear models, highlighting differences in instability behavior.

Findings

Density-dependent models exhibit specific instability sizes.

Comparison shows differences between density-dependent and non-linear models.

Distillation effects are analyzed in the context of these instabilities.

Abstract

Unstable modes in asymmetric nuclear matter (ANM) at subsaturation densities are studied in the framework of relativistic mean-field density-dependent hadron models. The size of the instabilities that drive the system are calculated and a comparison with results obtained within the non-linear Walecka model is presented. The distillation and anti-distillation effects are discussed.
