论文摘要
我们研究了从有效的现场理论方法开始量子重力的方法，从有效的田间理论方法开始，研究了四二齐（Reissner-Nordström）抗De Sitter的几何形状的量子重力校正。我们使用修饰的地平线半径的表达来计算量子校正后的wald熵，其表达在其他方法中再现了对数行为。我们进行热力学分析，并计算量子重力校正，以对温度，压力，比热和Helmholtz自由能。所有这些数量是重量量量量的组不变的。我们发现，量子充电的广告黑洞只能在有界的质量范围内存在，并且由于它从具有阳性比热的状态移动到负一个状态时，它可以进行二阶相变。
We study the quantum gravitational corrections to the geometry of a four-dimensionalcharged (Reissner-Nordström) Anti de Sitter black hole starting from an effective field theory approach to quantum gravity. We use the expression of the modified horizon radius to compute the quantum corrected Wald entropy, whose expression reproduces the logarithmic behaviour found by other methods. We perform a thermodynamics analysis and compute the quantum gravitational corrections to the temperature, pressure, specific heat and Helmholtz free energy. All these quantities are renormalisation group invariant. We find that a quantum charged AdS black hole can exist only for a bounded range of masses and that it can undergo a second order phase transition as it moves from a state with positive specific heat to a negative one.
