Abstract

In a recent paper, we studied a modified version of the Einstein–Rosen bridge. This modified bridge is traversable and works as a one-way membrane: a particle on the first sheet falling towards the throat will reach it in finite time (in Eddington coordinates), and will continue its trajectory on the second sheet. In this paper, we show that the particle undergoes a PT-symmetry as it crosses the throat. This could lead to observable effects thanks to an additional ingredient proposed by Einstein and Rosen: congruent points on the two sheets are identified. We propose a bimetric model to realize this identification for our modified bridge

单向虫洞中的 PT 对称性
在最近的一篇论文中,我们研究了爱因斯坦-罗森桥的改进版。这个改进版的桥是可穿越的,并且作为单向膜工作:在第一片上的粒子落向喉部,将在有限时间内到达喉部(在爱丁顿坐标中),并在第二片上继续其轨迹。在本文中,我们展示了粒子在穿过咽喉时的 PT 对称性。由于爱因斯坦和罗森提出了一个额外的要素:识别两片上的全等点,这可能会导致可观测的效应。我们提出了一个双测模型,以实现对我们的改良桥梁的这种识别。

期刊介绍: Annals of Physics presents original work in all areas of basic theoretic physics research. Ideas are developed and fully explored, and thorough treatment is given to first principles and ultimate applications. Annals of Physics emphasizes clarity and intelligibility in the articles it publishes, thus making them as accessible as possible. Readers familiar with recent developments in the field are provided with sufficient detail and background to follow the arguments and understand their significance. The Editors of the journal cover all fields of theoretical physics. Articles published in the journal are typically longer than 20 pages.
