摘要

在这项研究中，我们在爱因斯坦-麦克斯韦理论中提出了一个新的解决方案，该解决方案代表了包含Manko–Ruiz参数的磁化Taub–NUT时空。我们研究了这个时空的各个方面，包括它的曲率、闭合的类时间曲线和电磁场。此外，我们还利用隧道图像探索了磁化时空中的霍金辐射现象。我们的发现揭示了具有Manko–Ruiz参数的磁化Taub–NUT时空的独特特征和物理意义。

Properties of Melvin–Taub–NUT spacetime with Manko–Ruiz parameter

In this study, we present a novel solution in Einstein–Maxwell theory that represents the magnetized Taub–NUT spacetime incorporating the Manko–Ruiz parameter. We investigate various aspects of this spacetime, including its curvature, closed timelike curve, and electromagnetic fields. Additionally, we explore the phenomenon of Hawking radiation within this magnetized spacetime by employing the tunneling picture. Our findings shed light on the unique characteristics and physical implications of the magnetized Taub–NUT spacetime with the Manko–Ruiz parameter.

期刊介绍： General Relativity and Gravitation is a journal devoted to all aspects of modern gravitational science, and published under the auspices of the International Society on General Relativity and Gravitation. It welcomes in particular original articles on the following topics of current research: Analytical general relativity, including its interface with geometrical analysis Numerical relativity Theoretical and observational cosmology Relativistic astrophysics Gravitational waves: data analysis, astrophysical sources and detector science Extensions of general relativity Supergravity Gravitational aspects of string theory and its extensions Quantum gravity: canonical approaches, in particular loop quantum gravity, and path integral approaches, in particular spin foams, Regge calculus and dynamical triangulations Quantum field theory in curved spacetime Non-commutative geometry and gravitation Experimental gravity, in particular tests of general relativity The journal publishes articles on all theoretical and experimental aspects of modern general relativity and gravitation, as well as book reviews and historical articles of special interest.
