论文摘要
在存在字符串云的情况下，我们为爱因斯坦重力构建了一个精确的黑洞溶液，并与非线性电动力学（对应于弱场极限的麦克斯韦电动力学）。我们研究黑洞溶液的热力学特性，并得出校正的热力学第一法。弦云的存在不会影响当前黑洞的稳定性。但是，该系统处于临界范围半径上存在二阶相变。此外，我们研究了准模式及其阴影半径。此外，我们发现，随着理论的变化，该理论的参数显示了黑洞溶液的光学特征的不同方面。
We construct an exact black hole solution for the Einstein gravity coupled with the nonlinear electrodynamics (which corresponds to the Maxwell electrodynamics in the weak field limit) in the presence of a cloud of strings as the source. We study the thermodynamical properties of the black hole solutions and derive the corrected first-law of thermodynamics. The presence of a cloud of strings does not affect the stability of the present black hole. However, a second-order phase transition exists for this system at a critical horizon radius. Furthermore, we study the quasinormal modes and their shadow radius. In addition, we find that, upon variation, the parameters of the theory show different aspects of the optical characteristics of the black hole solutions.
