摘要:

在这篇工作中,我们研究了在一个圈状量子黑洞(称为自对偶黑洞)的时空中,与引力具有非最小耦合的大质量标量场的拟正规模。这样,我们用三阶WKB方法计算了特征频率,验证了特征频率与标量场的质量、与引力的非最小耦合参数以及圈量子引力参数之间的强相关性。从我们的结果中,我们可以检查,自对偶黑洞是稳定的标量扰动下,假设小的参数值。此外,这些结果告诉我们,对于场的质量为零且非最小耦合假定为$ξ=0$和$ξ=1/6$的情况,准正规模假定不同的值,即,在圈量子黑洞的背景下可以看到共形不变性的可能破坏。

英文摘要:

In this work, we investigate the quasinormal modes for a massive scalar field with a nonminimal coupling with gravity in the spacetime of a loop quantum black hole, known as the Self-Dual Black Hole. In this way, we have calculated the characteristic frequencies using the 3rd order WKB approach, where we can verify a strong dependence with the mass of scalar field, the parameter of nonminimal coupling with gravity, and parameters of the Loop Quantum Gravity. From our results, we can check that the Self-Dual Black Hole is stable under the scalar perturbations when assuming small values for the parameters. Also, such results tell us that the quasinormal modes assume different values for the cases where the mass of field is null and the nonminimal coupling assumes $ξ=0$ and $ξ=1/6$, i.e., a possible breaking of the conformal invariance can be seen in the context of loop quantum black holes.
