摘要

我们研究了 f(Q) 引力下黑洞（BH）周围的粒子动力学。首先，我们研究了f(Q)引力参数对黑洞的视界结构、光子轨道和大质量粒子最内层稳定圆轨道（ISCO）半径的影响。我们进一步研究了 f(Q) 引力参数对 BH 投下的阴影的影响。此外，我们还使用一般方法考虑了弱引力透镜现象，并探讨了在均匀和非均匀等离子体介质中，f(Q)引力下光束围绕 BH 的偏转角。

Particle dynamics, black hole shadow and weak gravitational lensing in the f (Q) theory of gravity

We study the particle dynamics around a black hole (BH) in f(Q) gravity. First, we investigate the influence of the parameters of f(Q) gravity on the horizon structure of the BH, photon orbits and the radius of the innermost stable circular orbit (ISCO) of massive particles. We further study the effects of the parameters of f(Q) gravity on the shadow cast by the BH. Moreover, we consider weak gravitational lensing using the general method, where we also explore the deflection angle of light rays around the BH in f(Q) gravity in uniform and nonuniform plasma mediums.
