AI中文摘要：
本研究基于该领域此前的工作，采用类托马斯-费米模型与贝特模型构建的夸克胶子等离子体（QGP）各组分的态密度展开。研究通过纳入并改变化学势与磁场，分析夸克胶子等离子体液滴的稳定性；引入有效质量项以描述夸克与胶子的静质量及热力学质量项，还将不同介子（K介子）纳入液滴介质。通过计算系统自由能并考察其随液滴半径、化学势及磁场的变化，确定稳定液滴形成的条件。研究发现，含π介子的现有介质与K介子介质可提升系统稳定性；化学势与磁场参数因作用相反，有助于约束液滴；进一步对熵与热容的计算，可获取系统相变性质的相关信息。本研究的分析与结果符合格点QCD模拟的结论。
英文摘要：
We build upon the previous studies conducted in this domain using the density of states of various components of the quark-gluon plasma(QGP) modelled after the Thomas-Fermi and Bethe models. This study provides an analysis of the stability of the quark-gluon plasma droplet by the inclusion and variation of chemical potential and magnetic field. An effective mass term is included to account for both the rest mass and thermodynamic mass terms of the quarks and gluon. We also expand on the inclusion of a different meson, kaon, into the medium of the droplet. The analysis on these quantities is done by calculating the free energy of the system and examining it as a function of droplet radius, chemical potential and magnetic field to find conditions for stable droplet formation. We discover that a kaonic medium, along with a pre-existing pionic medium, provides greater stability to the system. At the same time, it is realised that the parameters of chemical potential and magnetic field, due to their opposing effect, help in containing the droplet. Further calculations on entropy and heat capacity yield information about the nature of the phase transition of the system. Our analysis and results are in accordance with lattice QCD simulations.
