QED对Euler-Heisenberg-AdS黑洞相变和Ruppeiner几何的影响
QED effects on phase transition and Ruppeiner geometry of Euler-Heisenberg-AdS black holes
摘要：
考虑量子电动力学（QED）效应，在扩展相空间中研究了Euler-Heisenberg anti-de Sitter黑洞的黑洞相变和Ruppeiner几何.对于负的和小的正QED参数，我们分别观察到一个小/大黑洞相变和重入相变。而QED参数的大正值破坏了相变。每种情况下的相图明确展出。然后在热力学参数空间中构造Ruppeiner几何。对于小/大黑洞相变和重入相变两种情况，相应的标量曲率具有不同的特征。特别令人感兴趣的是，一个额外的区域的正标量曲率表示占主导地位的排斥相互作用之间的黑洞微结构是目前的黑洞与一个小的正QED参数。此外，对于Ruppeiner几何的标量曲率，也观察到普遍的临界现象。这些结果表明，QED参数对黑洞的相变和微观结构有着决定性的影响。
英文摘要：
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.
