[统计数据] 相对论性核状态方程的非扩展效应 [推广有奖]

摘要翻译：
Walecka多体场理论是在量子非扩展统计力学的背景下研究的，其特征是一个无量纲参数q$。我们考虑用幂律分布来统计描述核物质，它推广了标准的费米-狄拉克分布($q=1$)。我们发现，由于非扩展效应($q\neq1$)，标量和矢量介子场变得更强。通过数值处理，我们还表明，随着非扩展参数q$的增大，核子有效质量减小，状态方程变得更加僵硬。最后，对于温度在14MeV$<K_BT<$20MeV范围内的等温线，通常的麦克斯韦结构似乎是不必要的。

英文摘要：
  The Walecka many-body field theory is investigated in the context of quantum nonextensive statistical mechanics, characterized by a dimensionless parameter $q$. We consider nuclear matter described statistically by a power-law distribution which generalizes the standard Fermi-Dirac distribution ($q = 1$). We show that the scalar and vector meson fields become more intense due to the nonextensive effects ($q \neq 1$). From a numerical treatment, we also show that as the nonextensive parameter $q$ increases, the nucleon effective mass diminishes and the equation of state becomes stiffer. Finally, the usual Maxwell construction seems not to be necessary for isotherms with temperatures in the range 14 Mev$<k_BT<$20 MeV.
