论文摘要
当量子电动力学中的真空极化（QED）发生时，电磁场（EMF）之间的非线性相互作用发生。非线性电动力学的领域可能是由于这种相互作用而导致的，可能会对黑洞物理产生重要影响。本文考虑了爱因斯坦 - 非线性电动力学（NLE）领域的渐近平坦黑洞溶液。我们使用Novikov-Thorne模型研究了NLE参数对黑洞偏转角度的影响，使用Novikov-Thorne模型，使用弱场限制，使用Novikov-Thorne模型在弱场限制，阴影铸造的效果。特别是，我们研究了时间平均的能量通量，磁盘温度，差异亮度，不同的发射曲线和插入球形吸积。然后，我们展示了物理量如何取决于$β$和$ c $ nle的参数，并使用来自EHT的M87*和SGR A*的NLE参数提供了一些约束。
Non-linear interaction between the electromagnetic fields (EMF) occurs when vacuum polarization in quantum electrodynamics (QED) happens. The field of non-linear electrodynamics, which may result from this interaction, could have important effects on black hole physics. This paper considers the asymptotically flat black hole solution in Einstein-nonlinear electrodynamics (NLE) fields. We study the effect of the NLE parameters on the black hole deflection angle using the Gauss-Bonnet theorem in weak field limits, shadow cast using the null geodesics method, and thin accretion disk using the Novikov-Thorne model. In particular, we studied the time-averaged energy flux, the disk temperature, the differential luminosity, the different emission profiles, and infalling spherical accretion. Then we show how the physical quantities depend on $β$ and $C$ parameters of NLE and provide some constraints on the NLE parameters using the observations of M87* and Sgr A* from EHT.
