论文摘要
除了一个例外，所有已知的非苏匹马对称广告$ _4 $和广告$ _5 $ _5 $ _5 $的最大超级真空吸尘器已显示为字符串和m理论的模式低于BF绑定。其余的非对称ADS溶液在测量最大超级重力中具有扰动稳定，因此，基于弱重力构想的近期对ADS稳定性的猜想似乎与近期的猜想相矛盾。我们表明，通过展示一个新的衰减通道，这种解决方案实际上是不稳定的，只有在将解决方案提升到11个维度时才可见。特别是，内部歧管内部的通用位置的M2 brane探针被庞加莱地平线吸引，但仅在内部歧管的某些方向上被驱逐为“ brane jet”。这种不稳定性可能在任何维度的任何非s骨广告真空中都会出现。当存在爆炸射流不稳定时，排出麸皮的力与探针勃雷感受到的力相同，探针的质量小于其电荷。
With one exception, all known non-supersymmetric AdS$_4$ and AdS$_5$ vacua of gauged maximal supergravities that descend from string and M theory have been shown to have modes with mass below the BF bound. The remaining non-supersymmetric AdS solution is perturbatively stable within gauged maximal supergravity, and hence appears to contradict recent conjectures about the AdS stability based on the weak gravity conjecture. We show that this solution is actually unstable by exhibiting a new decay channel, which is only visible when the solution is uplifted to eleven dimensions. In particular, M2 brane probes at generic locations inside the internal manifold are attracted to the Poincaré horizon, only to be expelled as "brane jets" along certain directions of the internal manifold. Such instabilities can arise in any non-supersymmetric AdS vacuum in any dimension. When a brane-jet instability is present, the force that expels the branes is the same as the force felt by a probe brane whose mass is less than its charge.
