反de Sitter空间中黑洞的拟正规模:程函极限的数值研究

Quasinormal modes of black holes in anti-de Sitter space: a numerical study of the eikonal limit

Jaqueline Morgan, Vitor Cardoso, Alex S. Miranda, C. Molina, Vilson T. Zanchin

摘要:

利用级数解和时域演化方法,我们研究了反德西特背景下大黑洞和黑膜的引力和标量场拟正规模的程函极限。这些结果是特别相关的AdS/CFT对应,因为程函制度的特点是存在长寿命的模式(大概)主导的扰动的衰减时间尺度。我们证实了Festuccia和Liu(arXiv:0811.1033)预测的标量场(张量型引力)波动的慢阻尼模式的所有主要定性特征。然而,定量地,我们发现尺寸依赖的校正因子。我们还研究了QNM频率与黑洞(膜)视界半径以及矢量型和标量型引力扰动的角动量(波数)的关系。

英文摘要:

Using series solutions and time-domain evolutions, we probe the eikonal limit of the gravitational and scalar-field quasinormal modes of large black holes and black branes in anti-de Sitter backgrounds. These results are particularly relevant for the AdS/CFT correspondence, since the eikonal regime is characterized by the existence of long-lived modes which (presumably) dominate the decay timescale of the perturbations. We confirm all the main qualitative features of these slowly-damped modes as predicted by Festuccia and Liu (arXiv:0811.1033) for the scalar-field (tensor-type gravitational) fluctuations. However, quantitatively we find dimensional-dependent correction factors. We also investigate the dependence of the QNM frequencies on the horizon radius of the black hole (brane) and the angular momentum (wavenumber) of vector- and scalar-type gravitational perturbations.
