论文摘要
在本文中，我们研究了爱因斯坦四分之一的重力，在四个维度上与电动力学耦合。首先，通过变异作用，我们获得了场方程，并通过整合，我们获得了公制函数以及电磁电位的非线性三阶微分方程。然后，在麦克斯韦场的背景下，我们讨论了带电的黑洞存在的条件。然后，我们已经证明了四分之一理论阳性耦合的溶液的热力学和稳定性。最后，我们证明了EQG的带电的黑洞溶液（与GR和ECG不同）没有内在的地平线，并且不符合GR的极端结合。而且，BH解决方案在该理论中的独特性不再起作用。
In this paper, we studied Einsteinian quartic gravity minimally coupled to electrodynamics in four dimensions. First, by variation action, we obtain the field equations, and by integration, we obtain a nonlinear third-order differential equation for the metric function and as well as the electromagnetic potential. Then, in the context of the Maxwell field, we discussed the conditions under which the charged black hole exists. Then, we have demonstrated the thermodynamics and stability of the solution for the case of positive coupling of quartic theory. Finally, we showed that the charged black hole solutions of EQG (unlike GR and like ECG) have no inner horizon and do not conform to the extremal bound of GR. Also, the uniqueness of BH solutions in this theory does not work anymore.
