We study the possibility of constructing thin-shell wormhole (TSW) in a particular \(f\left( R\right) \)-gravity model with nonconstant Ricci scalar and coupled minimally with nonlinear electromagnetic fields. In doing so, first we give a new static spherically symmetric solution of the theory. Then we apply the cut-and-paste method to construct the TSW. As \(f^{\prime \prime \prime }\left( R\right) \ne 0\) we use the specific junction conditions to match the two spacetimes. We find the exact equilibrium radius of the shell from non-black hole solution and show that a linear perturbation leaves the TSW stable.

f(R)重力作用下的薄壳虫洞与非线性电动力学耦合
我们研究了在具有非恒定Ricci标量且最小程度与非线性电磁场耦合的特定\(f \ left(R \ right)\)-重力模型中构造薄壳虫洞(TSW)的可能性。为此,我们首先给出该理论的一个新的静态球对称解。然后,我们使用剪切粘贴方法来构造TSW。由于\(f ^ {\ prime \ prime \ prime} \ left(R \ right)\ ne 0 \),我们使用特定的结点条件来匹配两个时空。我们从非黑洞解中找到了壳的精确平衡半径,并表明线性扰动使TSW保持稳定。
