Abstract

In their Letter [Phys. Rev. Lett. 126, 101102 (2021); arXiv: 2010.07317], J.L. Blázquez-Salcedo, C. Knoll, and E. Radu have constructed a very interesting class of wormhole solutions in general relativity (GR), supported by a pair of classical charged spinor fields obeying the Dirac equation. The main new feature of these solutions is that such Dirac spinor fields can possess exotic properties, necessary for the existence of static wormhole configurations in GR. The present note contains a few remarks clarifying some points concerning this approach.

关于“爱因斯坦-狄拉克-麦克斯韦理论中可穿越虫洞”的注解

在他们的信中[物理学]Rev. Lett. 126, 101102 (2021);[j]， J.L. Blázquez-Salcedo, C. Knoll和E. Radu构造了一类非常有趣的广义相对论(GR)虫洞解，由一对经典带电旋量场支持，服从狄拉克方程。这些解的主要新特征是，这样的狄拉克旋量场可以具有奇异的性质，这是GR中静态虫洞构型存在所必需的。本注释包含一些注释，澄清有关这种方法的一些要点。

期刊介绍： Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoplesâ€™ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
