On growth of spinodal instabilities in nuclear matter

TL;DR

This paper investigates the early development of density fluctuations in nuclear matter within the spinodal region, using a stochastic mean-field approach that includes both collective and non-collective modes for a comprehensive analysis.

Contribution

It introduces a complete treatment of density correlation functions by incorporating non-collective modes into the stochastic mean-field framework for nuclear matter.

Findings

Inclusion of non-collective modes enhances the understanding of density fluctuation growth.

The approach provides a more complete description of spinodal instabilities.

Results are applicable to symmetric nuclear matter in a non-relativistic semi-classical framework.

Abstract

Early growth of density fluctuations of nuclear matter in spinodal region is investigated employing the stochastic mean-field approach. In contrast to the earlier treatments in which only collective modes were included in the calculations, in the present work non-collective modes are also included, thus providing a complete treatment of the density correlation functions. Calculations are carried out for symmetric matter in non-relativistic framework using a semi-classical approximation.
