论文摘要
我们在Einstein-Dirac-Maxwell理论中以四个时空维度构建了一类可穿越的虫洞的特定例子，而无需任何形式的异国情调。我们限制在单旋纺纱态处具有两个巨大费米的模型，我们显示了球形对称的渐近构型的存在，这些配置不含奇异性，代表了局部状态。这些解决方案满足了广义的Smarr关系，与极端的Reissner-Nordström黑洞有关。他们还拥有有限的质量$ m $和电荷$ q_e $，$ q_e/m> 1 $。还报道了带有未加入，无质量费米的确切虫洞溶液。
We construct a specific example of a class of traversable wormholes in Einstein-Dirac-Maxwell theory in four spacetime dimensions, without needing any form of exotic matter. Restricting to a model with two massive fermions in a singlet spinor state, we show the existence of spherically symmetric asymptotically flat configurations which are free of singularities, representing localized states. These solutions satisfy a generalized Smarr relation, being connected with the extremal Reissner-Nordström black holes. They also possess a finite mass $M$ and electric charge $Q_e$, with $Q_e/M>1$. An exact wormhole solution with ungauged, massless fermions is also reported.
