标题： Slow-rotating charged black hole solution in dynamical Chern-Simons modified gravity

摘要： 陈-西蒙斯（CS）引力是爱因斯坦广义相对论（GR）的一种修正理论。 CS理论来源于弦理论的低能极限，该理论涉及对爱因斯坦-希尔伯特作用量的异常修正。 CS项由庞特里亚金密度与标量场的乘积给出。 在本研究中，我们推导出一个带电的缓慢旋转黑洞（BH）解。 这种BH解的主要动机是轴对称且静态的，并且以偶极标量场形式扭曲了Kerr-Newman BH解。 此外，我们研究了度规的渐近修正，该修正与到BH的径向距离的七次方成反比，这表明它将逃逸任何来自弱场实验的有意义约束。 为了通过观测找到这种BH，我们研究了靠近BH的光子传播，并表明左旋偏振与右旋偏振之间的差异可能比Kerr-Newman BH的情况更强。 最后，我们使用测地线偏差推导了稳定性条件。 显示英文摘要

摘要： The Chern-Simons (CS) gravity is a modified theory of Einstein's general relativity (GR). The CS theory arises from the low energy limit of string theory which involves anomaly correction to the Einstein-Hilbert action. The CS term is given by the product of the Pontryagin density with a scalar field. In this study, we derive a charged slowly rotating black hole (BH) solution. The main incentives of this BH solution are axisymmetric and stationary and form distortion of the Kerr-Newman BH solution with a dipole scalar field. Additionally, we investigate the asymptotic correction of the metric with the inverse seventh power of the radial distance to the BH solution, This indicates that it will escape any meaningful constraints from weak-field experiments. To find this kind of BHs by observations, we investigate the propagation of the photon near the BH and we show that the difference between the left-rotated polarization and the right-handed one could be observed as stronger than the case of the Kerr-Newman BH. Finally, we derived the stability condition using the geodesic deviations.
