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.

变量状态方程对非线性电动力学薄壳虫洞稳定性的影响

本文探讨了非线性电动力学对由 Reissner-Nordström 黑洞的两个等价几何结构和非线性电动力学制定的薄壳虫洞的稳定配置的作用。为此,我们使用剪切和粘贴方法来消除黑洞几何的中心奇点和事件视界。然后,我们通过考虑位于薄壳的不同类型的物质分布,即正压模型和可变状态方程(幻影变量和 Chaplygin 变量模型)来探索所开发模型的稳定性。我们使用线性化径向扰动来探索薄壳虫洞的稳定特性。有趣的是,Schwarzschild 和 Reissner-Nordström 黑洞显示出此类物质分布的不稳定构型,而具有非线性电动力学的 Reissner-Nordström 黑洞则表现出稳定区域。人们发现,非线性电动力学的存在为正压模型和变量模型提供了稳定结构的可能性。可以得出结论,通过考虑更高的耦合常数负值,这些模型的稳定区域增加α和真正的常数n.
