非广延效应对QHD相结构的影响
Nonextensive effects on the phase structure of QHD
摘要：
在Walecka多体场论的背景下，研究了非广延效应对核物质相变的影响。当计算的结果为核物质在消失的重子密度相比，通过标准的费米-狄拉克分布得到的一般行为的变化进行了观察。观察到非广延参数$q$和相变的耦合常数$C_S^2$之间的依赖性。还提出了一个数值关系，这种化学依赖性。
英文摘要：
We investigate nonextensive effects on phase transition in nuclear matter in the context Walecka many-body field theory. Changes in the general behavior are observed when the results calculated for the nuclear matter at vanishing baryon density are compared to those obtained through the standard Fermi-Dirac distribution. It is observed a dependence between the nonextensive parameter $q$ and the coupling constants $C_S^2$ of the phase transition. A numerical relation for this thermodynamical dependence is also proposed.
