标题： Thermal fluctuation, deflection angle and greybody factor of a high-dimensional Schwarzschild black hole in STVG

摘要： 在本工作中，我们研究标量-张量-矢量引力（STVG）中高维施瓦茨希尔德黑洞的热涨落、偏转角和灰体因子。 基于热涨落对黑洞熵的修正，我们计算了一些与黑洞熵修正相关的热力学量。 详细讨论了一阶和二阶修正、时空维度以及STVG参数对这些热力学量的影响。 此外，通过利用高斯-博内定理，在弱场极限下得到了偏转角，并可视化了两个参数对结果的影响。 最后，我们计算了无质量标量场的灰体因子的界限。 显示英文摘要

摘要： In this work, we study the thermal fluctuation, deflection angle and greybody factor of the high-dimensional Schwarzschild black hole in scalar-tensor-vector gravity (STVG). Based on the correction of black hole entropy due to thermal fluctuation, we calculate some thermodynamic quantities associated with the correction of black hole entropy. The influence of the first-order and second-order corrections, spacetime dimensionality and STVG parameters on these thermodynamics quantities are discussed in detail. Additionally, by utilizing the Gauss-Bonnet theorem, the deflection angle is obtained in the weak field limit and the effect of two parameters on the results is visualized. Finally, we calculate the bounds on greybody factors of a massless scalar field.
