论文摘要
虫洞桥接宇宙的遥远地方是广义相对论的众所周知的解决方案。尤其是，允许星际旅行的可穿越的虫洞在科幻小说中也很受欢迎。但是，尚未发现它们存在的暗示。在这项工作中，我们建议使用从球形虫洞散射的引力波（GW）来寻找它们的存在。我们仔细地通过时间无关的散射理论来计算反射和传输波形。我们的结果定量显示了虫洞两侧两个宇宙中的回声签名。在一定的虫洞质量范围内，传输波具有无灵感波形的独特孤立呼叫，并且反射波具有反chirp的行为，即缺失chiring信号。我们还计算了当前和投影的GW望远镜的搜索范围。我们的方法可以适应有效计算模板以搜索虫洞。
Wormholes bridging distant places of the universe are well-known solutions of general relativity. In particular, traversable wormholes which allow interstellar traveling are also popular in science fiction. However, no hint of their existence has been found yet. In this work, we propose using the gravitational wave (GW) scattering off spherical wormholes to search for their existence. We carefully calculate the reflected and transmitted waveforms with time-independent scattering theory. Our results quantitatively show the echo signatures in the two universes on both sides of the wormhole. In a certain wormhole mass range, the transmitted wave has a unique isolated chirp without an inspiral waveform, and the reflected wave has the anti-chirp behavior, i.e., the missing of the chirping signal. We also calculate the searching range of the current and projected GW telescopes. Our method can be adapted to efficiently calculate the templates to search for wormholes.
