论文摘要
我们介绍了混合Quark-Meson-Nucleon模型的最新进展,该模型统一了Quark和Hadroonic自由度的热力学。所获得的状态方程与饱和密度下的核物质特性以及重离子碰撞实验的流量约束。计算了紧凑型恒星的质量 - 拉迪乌斯关系和潮汐变形,并将其与最新的天体物理观测值进行了比较。同时研究了净 - 巴里昂数字的高阶累积物,也研究了同义 - 偏金属物质的相图。
We present the recent progress of the hybrid quark-meson-nucleon model for multi-messenger astronomy that unifies the thermodynamics of quark and hadronic degrees of freedom. The obtained equation of state is in accordance with nuclear matter properties at saturation density and with the flow constraint from heavy ion collision experiments. The mass-radius relations and tidal deformabilities for compact stars are calculated and compared with the latest astrophysical observations. The phase diagram of the isospin-symmetirc matter is studied as well in terms of the higher-order cumulants of the net-baryon number.
