粒子探测器在时序危险下的行为

Particle detectors under chronological hazard

Ana Alonso-Serrano, Erickson Tjoa, Luis J. Garay, Eduardo Martín-Martínez

AI总结:

本研究通过局部粒子探测器在因果断开区域探测闭合类时曲线,证明探测器可区分拓扑与几何信息,并识别无CTCs的周期性时空、曲率及时间机器时空。

摘要:

我们分析了如何通过将局部粒子探测器放置在与时环(CTCs)因果断开的时空区域中,来辨别表征时间机器的闭合类时曲线(CTCs)的存在。我们的研究表明,探测器不仅能判断是否存在CTCs,还能分离拓扑与几何信息,并区分无CTCs的周期性时空(如爱因斯坦圆柱)、曲率以及具有可实现时间机器的拓扑识别的时空。

英文摘要:

We analyze how the presence of closed timelike curves (CTCs) characterizing a time machine can be discerned by placing a local particle detector in a region of spacetime which is causally disconnected from the CTCs. Our study shows that not only can the detector tell if there are CTCs, but also that the detector can separate topological from geometrical information and distinguish periodic spacetimes without CTCs (like the Einstein cylinder), curvature, and spacetimes with topological identifications that enable time-machines.
