论文摘要
当最长的寿命模式是具有较高角数的模式时,出现了准模式的异常衰减速率。最近在两种情况下都观察到了这种行为,最近在不同的静态空间中研究了这种行为,以实现未充电的标量和费米子扰动。在这项工作中,我们考虑了在Reissner-Nordström-De保姆的背景下带电的大规模标量场的传播黑洞,我们主要研究标量场电荷在准频率光谱中的影响,以及其对异常衰变率的影响。主要是,我们还表明,对于大量带电的标量字段也存在异常行为,并且存在标量场质量的临界值,除了行为倒置之外。但是,也存在标量场和黑洞电荷的参数$ qq $的临界值,当宇宙常数增加时,它会增加衰减率的异常行为时,可以避免基本模式的异常行为。
The anomalous decay rate of the quasinormal modes occurs when the longest-lived modes are the ones with higher angular number. Such behaviour has been recently studied in different static spacetimes, for uncharged scalar and fermionic perturbations, being observed in both cases. In this work we consider the propagation of charged massive scalar fields in the background of Reissner-Nordström-de Sitter black holes and we mainly study the effect of the scalar field charge in the spectrum of quasinormal frequencies, as well as, its effect on the anomalous decay rate. Mainly, we show that the anomalous behaviour is present for massive charged scalar fields as well, and a critical value of scalar field mass exists, beyond which the behaviour is inverted. However, there is also a critical value of the parameter $qQ$ of the charge of the scalar field and of the charge of the black hole, which increases when the cosmological constant increases, and beyond the critical value the anomalous behaviour of the decay rate could be avoided for the fundamental mode.
