摘要：
在本文中，我们考察了旋转黑洞背景下重夸克偶素的热力学。具体而言，我们从热力学关系出发，研究角动量对重夸克偶素的夸克间距、自由能、结合能、熵、熵力和内能的影响。我们的结果表明，角动量会减小夸克间距的最大值，这表明它促进了夸克偶素的解离。此外，我们观察到角动量会抑制自由能。从结合能的结果来看，角动量有利于介子熔解为自由的夸克和反夸克。而且，结果显示角动量会增加熵和熵力，从而加速夸克偶素的解离。在较大的夸克间距下，角动量会增加内能。最后，我们发现当夸克对 $Q\overline{Q}$ 的轴与角动量方向垂直时，角动量对夸克偶素的影响更为显著。
英文摘要：
In this paper, we examine the thermodynamics of heavy quarkonium in the spinning black hole background. Specifically, we investigate the effect of angular momentum on the interquark distance, free energy, binding energy, entropy, entropic force, and internal energy of heavy quarkonium from the thermodynamic relationship. Our findings indicate that the angular momentum reduces the maximum value of interquark distance, suggesting that it promotes the dissociation of quarkonium. Additionally, we observe that the angular momentum suppresses free energy. From the results of binding energy, the angular momentum favors the melting of meson into a free quark and antiquark. Moreover, the results show that angular momentum increases the entropy and entropic force, thus accelerates the dissociation of quarkonium. The angular momentum increases the internal energy at large interquark distance. Finally, we find that the angular momentum has a more pronounced effect on quarkonium when the axis of quark pair $Q\overline{Q}$ is transverse to the direction of angular momentum.
