论文摘要
我们在$ {\ cal n}中介绍了一个新的充电C-Metrics家族= 2 $四个维度的超级尺寸。 C-Metric的双芯旋转使我们能够将溶液带入Lü和Vázquez-Poritz先前发现的不同C-Metrics家族。在零加速度限制的情况下，我们的消失电荷的解决方案减少了标量的带有常规视野的广告中的黑色孔。然而，事实证明，每个中性解决方案的家族都无法通过事件视野遮盖曲率奇异性，表明它们俩都不代表带有标量头发的加速黑洞。只有在非散热器的情况下才能获得没有可见曲率奇点的物理溶液。详细阐明了解决方案的因果结构。我们还提出了溶液保留超对称性的条件。
We present a new family of charged C-metrics in ${\cal N}=2$ gauged supergravity in four dimensions. The double Wick rotation of the C-metric allows us to bring our solution into a different family of the C-metrics previously found by Lü and Vázquez-Poritz. In the case of zero acceleration limit, our solution with vanishing charges reduces to the scalar haired black holes in AdS with regular horizons. Nevertheless, it turns out that each family of neutral solutions fails to veil the curvature singularity by the event horizon, showing that neither of them represents the accelerated black holes with a scalar hair. Physical solutions without visible curvature singularities are obtained only in the case of nonvanishing charges. Causal structures of the solution are spelled out in detail. We also present conditions under which the solution preserves supersymmetry.
