一级相变核物质的物态方程

Equation of state of nuclear matter in the first order phase transition

Toshiki Maruyama, Toshitaka Tatsumi, Satoshi Chiba

摘要:

我们研究了核物质在一级相变(FOPT),如液-气相变、K介子凝聚和强子-夸克相变时的性质。作为由多种带电粒子组成的物质的FOPT的一般特征,由于两相之间的库仑排斥力和表面张力的平衡,出现了具有规则结构的混合相,称为“面食”。由于非均匀结构的影响,混合相的状态方程不同于整体应用Gibbs条件或Maxwell构造得到的状态方程。我们发现,电荷屏蔽和强大的表面张力,使状态方程接近的麦克斯韦建设。

英文摘要:

We investigate the properties of nuclear matter at the first-order phase transitions (FOPT) such as liquid-gas phase transition, kaon condensation, and hadron-quark phase transition. As a general feature of the FOPT of matter consisting of many species of charged particles, there appears a mixed phases with regular structures called "pasta" due to the balance of the Coulomb repulsion and the surface tension between two phases. The equation of state (EOS) of mixed phase is different from those obtained by a bulk application of Gibbs conditions or by the Maxwell construction due to the effects of the non-uniform structure. We show that the charge screening and strong surface tension make the EOS close to that of the Maxwell construction.
