论文摘要
我们考虑在Banados-teitelboim-Zanelli黑洞的近晶体几何形状中，在外部均匀磁场的作用下考虑了带电的标量场，并通过获得相应的Klein-Gordon方程的分析解决方案，并获得了所考虑的系统的准平稳状态。我们获得了方程的溶液函数，因此我们到达复杂的光谱。我们观察到模式的实际振荡频率及其衰减时间取决于除几何背景的参数外，外部磁场的强度。我们看到，随着外部磁场的强度的增加，真实振荡模式的幅度降低了，并且模式的衰减时间变得更长。结果还表明，在这样的扰动场下，几何背景是稳定的。
We consider a charged scalar field under the effect of an external uniform magnetic field in the near-horizon geometry of the Banados-Teitelboim-Zanelli black hole with torsion and obtain quasi-stationary states of the system under consideration through obtaining analytical solution of the corresponding Klein-Gordon equation. We obtain the solution function of the equation and accordingly we arrive at a complex spectra. We observe that the real oscillation frequency of the modes and their decay time depends on the strength of the external magnetic field besides the parameters of the geometric background. We see that the amplitude of the real oscillation modes decreases and the decay time of the modes becomes longer as the strength of the external magnetic field increases. The results also indicate that the geometric background is stable under such a perturbation field.
