论文摘要
我们使用Ruppeiner几何形状研究了Hayward-Ads黑洞的微观结构之间的相互作用。我们的研究表明，在温度和体积的参数空间的大部分时间里，黑洞分子之间的主要相互作用是有吸引力的，就像范德华系统一样。然而，与范德华流体相反，在某些参数范围内，小黑洞相位存在弱的优势排斥相互作用。该结果清楚地区分了带有磁性黑洞的相互作用与范德华流体的相互作用。但是，这类相互作用是带电黑洞的特征，因为它们不取决于磁电荷或温度。
We study the interaction between the microstructures of Hayward-AdS black hole using Ruppeiner geometry. Our investigation shows that the dominant interaction between the black hole molecules is attractive in most part of the parametric space of temperature and volume, as in van der Waals system. However, in contrast to the van der Waals fluid, there exists a weak dominant repulsive interaction for small black hole phase in some parameter range. This result clearly distinguishes the interactions in a magnetically charged black hole from that of van der Waals fluid. However, these sort of interactions are characteristic for charged black holes since they do not dependent on magnetic charge or temperature.
