AdS中均匀黑弦的稳定化

Stabilizing Homogeneous Black Strings in AdS

Adolfo Cisterna, Carla Henriquez-Baez, Julio Oliva

摘要:

我们知道平坦时空中的均匀黑弦在长波长扰动下是不稳定的。最近,通过包含只依赖于扩展坐标的标量场,在存在负宇宙学常数的情况下构造了均匀黑弦,因此意味着一般扰动将包含度量和标量涨落。在这里,我们表明,对于这样的一般扰动均匀的黑弦与负宇宙学常数是微扰稳定的线性水平,无论大小的Schwarzschild-AdS黑洞位于膜上。

英文摘要:

It is known that homogenous black strings in flat spacetime are unstable under long wavelength perturbations. Recently, by including scalar fields that depend on the extended coordinates only, homogenous black strings have been constructed in the presence of a negative cosmological constant, therefore implying that generic perturbations will contain both metric and scalar fluctuations. Here we show that for such generic perturbations homogeneous black strings with a negative cosmological constant are perturbatively stable at linear level, regardless the size of the Schwarzschild-AdS black hole located on the brane.
