论文摘要
本文探讨了非线性电动力学对薄壳蠕虫的稳定构型的作用，该孔孔是由带有非线性电动力学的Reissner-Nordström黑洞的两个等效几何形式提出的。为此，我们使用切割和糊状方法来消除黑洞几何形状的中心奇异性和事件范围。然后，我们通过考虑位于薄壳的不同类型的物质分布，即预压模型和状态的可变方程（Phantomike变量和Chaplygin变量模型），从而探索了开发模型的稳定性。我们使用线性化的径向扰动来探索薄壳蠕虫的稳定特征。有趣的是，Schwarzschild和Reissner-Nordström黑洞显示了这种类型的物质分布的不稳定配置，而Reissner-Nordström黑洞的非线性电动力学表示稳定的区域。发现非线性电动力学的存在为压缩和可变模型提供了稳定的结构。得出的结论是，这些模型的稳定区域通过考虑耦合常数$α$和真正的常数$ n $的较高负值来增加。
This paper explores the role of nonlinear electrodynamics on the stable configuration of thin-shell wormholes formulated from two equivalent geometries of Reissner-Nordström black hole with nonlinear electrodynamics. For this purpose, we use cut and paste approach to eliminate the central singularity and event horizons of the black hole geometry. Then, we explore the stability of the developed model by considering different types of matter distribution located at thin-shell, i.e., barotropic model and variable equations of state (phantomlike variable and Chaplygin variable models). We use linearized radial perturbation to explore the stable characteristics of thin-shell wormholes. It is interesting to mention that Schwarzschild and Reissner-Nordström black holes show the unstable configuration for such type of matter distribution while Reissner-Nordström black hole with nonlinear electrodynamics expresses stable regions. It is found that the presence of nonlinear electrodynamics gives the possibility of a stable structure for barotropic as well as variable models. It is concluded that stable region increases for these models by considering higher negative values of coupling constant $α$ and the real constant $n$.
