论文摘要
这项研究探讨了核恒星物质的语音导热率,因为它经历了“拓扑”过渡到“面食”状态,并进一步向下到固液相变。该研究是使用嵌入有效(即Thomas-Fermi)库仑电位的核电位的分子动力学模拟进行的。热导率在t = 1 meV附近的狭窄温度间隔内经历了巨大的变化。这种变化实现了在加热过程中的“面食”分解。通过翻转质子或中子的速度通过翻转质子的导热率进一步显示了不对称核星形物质的脱钩。
This investigation explores the phononic thermal conductivity of nuclear star matter as it undergoes the "topological" transition to the "pasta" regime, and further down to the solid-liquid phase transition. The study was carried out using molecular dynamics simulations with nuclear potentials embedded in an effective (i.e. Thomas-Fermi) Coulomb potential. The thermal conductivity experiences a dramatic change within a narrow temperature interval around T=1 MeV. This change accomplishes the "pasta" breakdown during a heating process. The thermal conductivity by flipping protons' or neutrons' velocity further shows a decoupling for asymmetric nuclear star matter.
