摘要

本文给出了一个球对称虫洞与虚量场和非线性电磁场耦合的爱因斯坦引力。数值结果表明，该解违反了零能条件（NEC），且随着参数的变化，整个时空的ADM质量由正变为负。此外，我们还分析了溶液的光环（LR），并论证了其天文观测特性。特别是当负质量出现时，一般的LR不会出现，只有咽喉处存在“特殊的不稳定LR”，这是由虫洞两侧负质量的排斥作用造成的。最后绘制了反映虫洞几何特征的嵌入图。

Generalized Bronnikov–Ellis wormhole with nonlinear electromagnetic field

In this paper, we present a spherically symmetric wormhole in Einstein gravity coupled with the phantom scalar field and the nonlinear electromagnetic field. Numerical results show that this solution violates the Null Energy Condition (NEC), and as the parameters change, the ADM mass of the entire spacetime changes from positive to negative. In addition, we analyze the light ring (LR) of the solution and demonstrate the astronomical observation properties. Especially when negative mass appears, the general LR will not appear, only a “special unstable LR” exists at the throat, which is caused by the repulsive effect of the negative mass on both sides of the wormhole. Finally, we draw the embedding diagram to reflect the geometric characteristics of the wormhole.
