Hollow nuclear matter

TL;DR

This paper demonstrates through modeling that large or excited nuclear matter can be hollow, with the inner bubble size influenced by charge, challenging the traditional view of nuclei as always compact.

Contribution

It introduces the possibility of hollow nuclear matter using an isospin-dependent Boltzmann transport model, a novel concept in nuclear physics.

Findings

Large block and excited nuclear matter can be hollow.

Inner bubble size depends on nuclear charge.

Hollow nuclear matter has potential implications across physics fields.

Abstract

It is generally considered that an atomic nucleus is always compact. Based on the isospin-dependent Boltzmann nuclear transport model, here I show that large block nuclear matter or excited nuclear matter may both be hollow. And the size of inner bubble in these matter is affected by the charge number of nuclear matter. Existence of hollow nuclear matter may have many implications in nuclear or atomic physics or astrophysics as well as some practical applications.
