摘要

在这篇研究论文中，我们研究了旋转 ModMax 黑洞的视界和麦积层结构。通过研究最内稳定圆轨道（ISCO）的特征和有效势的行为，分析了测试粒子的运动。本研究探讨了旋转 ModMax 黑洞的不同屏蔽因子 γ 和 Q 电荷值。此外，我们还研究了几个热力学量，如黑洞的焓、霍金温度、吉布斯自由能和熵。此外，我们还简要研究了与该黑洞相关的特定参数值下两个粒子碰撞所产生的质量中心能量（CM）（包括极值和非极值情况）。

Particle dynamics and thermodynamical analysis of the rotating ModMax black holes

In this research paper, we investigate the structure of the horizon and ergosphere of a rotating ModMax black hole. The motion of test particles is analyzed by studying the characteristics of the innermost stable circular orbit (ISCO) and the behavior of the effective potential. Different values of the screening factor $γ$ and the $Q$ charge of the rotating ModMax black hole are explored in this study. Moreover, we also examine several thermodynamic quantities such as Enthalpy, Hawking temperature, Gibbs free energy, and entropy of the black hole. Additionally, the center-of-mass-energy (CM) generated by the collision of two particles (both in extremal and non-extremal cases) is briefly investigated for specific parameter values associated with this black hole.
