摘要

利用Eddington-inspired Born-Infeld (EiBi)理论研究了静态球对称带电黑洞的热力学性质。我们考虑麦克斯韦电动力学与幂律的物质场。在EiBI引力理论[1]中进行计算时，需要对黑洞熵进行修正，才能推导出黑洞质量。比热CQ由熵和霍金温度导出。结果表明，除了q=18(−3−41)、κ =1和q= 0.1外，大多数黑洞都存在。黑洞一开始在几个Q值下是不稳定的，但之后CQ呈指数增长并变为正值。

Study of thermodynamic properties for charged power law black holes in Eddington-inspired Born-Infeld theory

We study thermodynamic properties of static spherically-symmetric and electrically-charged black hole in Eddington-inspired Born-Infeld (EiBi) Theory. We consider Maxwell electrodynamics with power law for the matter fields. Corrected black hole entropy is needed when we evaluate in EiBI theory of gravity [1] and we can derived the black hole mass. Specific heat CQ is derive√d from entropy and Hawking temperature. Results show that mostly of the black holes exist except when q=18(−3−41), κ = 1 and Q = 0.1. Black holes are unstable at first for a few values of Q, but CQ increases exponentially afterwards and becomes positive.
