论文摘要
在这项工作中，我们考虑了爱因斯坦理论的黑洞解决方案，并与具有固定指数值的非线性幂律电磁场结合。我们研究了规范和宏伟的典型合奏中的扩展相空间动力学，其中变化的宇宙常数起有效热力压力的作用。我们检查了这种黑孔中的热力学相变，发现一阶和二阶相变可能发生在规范的集合中，而对于大规范的合奏，允许鹰派和二阶相变。
In this work we consider black hole solutions to Einstein theory coupled to a nonlinear power-law electromagnetic field with a fixed exponent value. We study the extended phase space thermodynamics in canonical and grand canonical ensembles where the varying cosmological constant plays the role of an effective thermodynamic pressure. We examine thermodynamical phase transitions in such black hols and find that both first and second order phase transitions can occur in the canonical ensemble, while for the grand canonical ensemble the Hawking-Page and second order phase transitions are allowed.
