We construct traversable wormholes in dilatonic Einstein-Gauss-Bonnet theory in four spacetime dimensions, without needing any form of exotic matter. We determine their domain of existence, and show that these wormholes satisfy a generalized Smarr relation. We demonstrate linear stability with respect to radial perturbations for a subset of these wormholes.
我们在具有四个时空维度的挠率爱因斯坦-高斯-博内理论中构造了可穿越虫洞,而无需任何形式的奇异物质。我们确定了它们的存在域,并表明这些虫洞满足广义 Smarr 关系。我们证明了这些虫洞中的一部分对于径向微扰是线性稳定的。
