TL;DR

This paper numerically investigates the 3D structures of low-density nuclear matter, revealing conventional pasta shapes and metastable mixtures, and discusses droplet lattice arrangements.

Contribution

It provides a detailed 3D numerical analysis of nuclear pasta structures without geometric assumptions, highlighting metastable states and lattice configurations.

Findings

Conventional pasta structures are confirmed.

Metastable mixtures of pasta structures are observed.

Lattice structures of droplets are discussed.

Abstract

We numerically explore the pasta structures and properties of low-density nuclear matter without any assumption on the geometry. We observe conventional pasta structures, while a mixture of the pasta structures appears as a metastable state at some transient densities. We also discuss the lattice structure of droplets.
