论文摘要
考虑到量子电动力学（QED）效应，我们研究了扩展相空间中的Euler-Heisenberg抗DE Sitter黑洞的黑洞相变和Ruppeiner几何形状。对于负和小QED参数，我们分别观察到一个小/大的黑洞相变和重进入相变。而QED参数的大正值破坏了相变。明确显示了每种情况的相图。然后，我们在热力学参数空间中构造Ruppeiner几何形状。针对小/大黑洞相变和重入相变的相应标量曲率的不同特征。特别令人感兴趣的是，对于黑洞，有一个较小的正QED参数的黑洞存在，表明黑洞微观结构中有主导的排斥相互作用的正面标态曲率的附加区域。此外，对于Ruppeiner几何形状的标量曲率，还观察到了普遍的关键现象。这些结果表明，QED参数对黑洞相变和微观结构的影响至关重要。
Taking the quantum electrodynamics (QED) effect into account, we study the black hole phase transition and Ruppeiner geometry for the Euler-Heisenberg anti-de Sitter black hole in the extended phase space. For negative and small positive QED parameter, we observe a small/large black hole phase transition and reentrant phase transition, respectively. While a large positive value of the QED parameter ruins the phase transition. The phase diagrams for each case are explicitly exhibited. Then we construct the Ruppeiner geometry in the thermodynamic parameter space. Different features of the corresponding scalar curvature are shown for both the small/large black hole phase transition and reentrant phase transition cases. Of particular interest is that an additional region of positive scalar curvature indicating dominated repulsive interaction among black hole microstructure is present for the black hole with a small positive QED parameter. Furthermore, the universal critical phenomena are also observed for the scalar curvature of the Ruppeiner geometry. These results indicate that the QED parameter has a crucial influence on the black hole phase transition and microstructure.
