摘要

我们最近对2味夸克磁化PNJL模型的研究工作已经扩展到\(2+1\)味夸克在热质量中的有限重子势和拉格朗日密度势中磁场的合作。结果给出了在热力学质量中加入有限化学势和在势中加入磁场后的状态方程及其相关热力学性质的评价。结果表明，有限重子化学势的加入使所有热力学参数都得到了改善。在有限重子密度下的结果也符合和改进了我们在没有重子化学势值的情况下的前期工作。这意味着在热质量中重子化学势的存在所预测的输出中有一个上升。

Thermodynamic equation of state of magnetized PNJL model of \(2+1\) flavor at finite baryonic density

Our recent research work for 2 flavor magnetized PNJL model has been extended to \(2+1\) flavor quarks cooperating the finite baryonic potential in the thermal mass and magnetic field in the potential of the Lagrangian density. The evaluation of equation of state and its relevant thermodynamic properties after incorporating the finite chemical potential in the thermal mass and magnetic field in the potential are represented in the results. The results show that all the thermodynamic parameters are found to be improved by the inclusion of the finite baryonic chemical potential. The result at the finite baryonic density also conforms and improves from our earlier work without the value of baryonic chemical potential. It means that there is an up-gradation in the outputs as predicted by the presence of baryonic chemical potential in the thermal mass.
