论文摘要
Morris-Thorne类型的几种可遍历的虫洞（T-WH）已被视为Einstein-nonlinelear extirotroynemics重力（GR-NLED）的精确溶液，例如\ cite {Arellano2009，Bronnikov2018，Bronnikov_walia2021，canate_breton2018，canate_breton_ortiz2020，canate_magos_breton2020}。但是，这些解决方案均未得到满足合理条件的非线性电动力学模型的支持。在这项工作中，我们介绍了第一个可遍历的爱因斯坦 - 非线性电动力学重力与自我相互作用的幻影标量标量场（GR-NLED-SF）搭配NLED模型，因此在弱场的限制中变成了Maxwell Electrovynalmics。此外，我们表明，这种新颖的T-WH时空也是Einstein-Scalar-Gauss-Bonnet（ESGB）理论的精确解决方案，具有非线性电动力学源，但现在具有真实的标量场具有阳性动力学术语。
Several traversable wormholes (T-WHs) of the Morris-Thorne type have been presented as exact solutions of Einstein-nonlinear electrodynamics gravity (GR-NLED), e.g. \cite{Arellano2009, Bronnikov2018,Bronnikov_Walia2021, Canate_Breton2018, Canate_Breton_Ortiz2020, Canate_Magos_Breton2020}. However, none of these solutions is support by a nonlinear electrodynamics model satisfying plausible conditions. In this work, we present the first traversable wormhole solution of Einstein-nonlinear electrodynamics gravity coupled to a self-interacting phantom scalar field (GR-NLED-SF) with a NLED model such that in the limit of weak field becomes the Maxwell electrodynamics, is presented. Furthermore, we show that this novel T-WH spacetime is also an exact solution of the Einstein-scalar-Gauss-Bonnet (EsGB) theory with a nonlinear electrodynamics source, but now with a real scalar field having a positive kinetic term.
