带电AdS黑洞的热力学极值关系

Universal thermodynamic extremality relations for charged AdS black hole surrounded by quintessence

Qiuhong Chen, Wei Hong, Jun Tao

摘要:

广义相对论的微扰修正得到了熵与极值的一般关系。这个关系在带电的AdS黑洞中是成立的,并扩展到旋转的大质量引力黑洞。本文确定了四维RN-AdS黑洞被精粹包围的普适关系,并找到了黑洞质量和与精粹密度有关的归一化因子$a$之间的一个新的极值关系.此外,我们还发现当黑洞熵增大时,修正常数为负,黑洞质量和质荷比减小,因此该黑洞表现出WGC行为.在此基础上,我们导出了非线性电动力学源耦合到具有经典场的AdS时空的一般关系式。我们发现了黑洞质量与磁荷$β$之间的另一个新的极值关系。

英文摘要:

The perturbation correction of general relativity has obtained the general relationship between entropy and extremality. The relation was found to exactly hold for the charged AdS black hole, and extended to the rotating and massive gravity black holes. In this paper, We confirm the universal relation for the four dimensional RN-AdS black hole surrounded by the quintessence, and find a new extremality relation between black hole mass and the normalization factor $a$ related to the density of quintessence. Besides, we also find that when the black hole entropy increases, the correction constant is negative, the black hole mass and the mass-charge ratio decreases, hence this black hole displays WGC-like behavior. Moreover, we derive the general relationship on nonlinear electrodynamic source couples to AdS spacetime with quintessence field. We find another new extremality relation between black hole mass and the magnetic monopole charge $β$.
