Abstract

We investigate the turnaround radius of the Reissner–Nordström deSitter Spacetime and how the turnaround radius changes if a test particle carries charge. We also consider the Martínez–Troncoso–Zanelli (MTZ) solution of conformally coupled gravity and investigate how the turnaround radius changes for a scalar test charge. In both scalar and electric interaction cases we find that the Turnaround Radius depends on the particle’s energy.

赖斯纳-诺德斯特伦德西特时空中带电粒子的回转半径

我们研究了赖斯纳-诺德斯特伦德西特时空的回转半径，以及如果测试粒子携带电荷，回转半径会如何变化。我们还考虑了共形耦合引力的马丁内斯-特隆科索-扎内利（Martínez-Troncoso-Zanelli，MTZ）解，并研究了标量测试电荷的回转半径是如何变化的。在标量和电相互作用情况下，我们都发现回转半径取决于粒子的能量。

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.
