论文摘要
我们分析了三维测量超级重力的``superstratum sector''中的BPS方程。我们获得了多参数超对称溶液，其中包括标准超质层的椭圆形变形。我们提升了三维溶液以获得相应的六维几何形状。这产生了椭圆形的，Ambi-Bolar Hyper-kähler几何形状的新家族，并具有四个维度，并具有非三型旋晶$ u（1）$等距。我们还找到了一个新的缩放级别superstrata家族，其s偶将完全生活在超级ns的NS领域，因此更适合使用字符串探针进行精确分析。在所有这些新的超质图中，包括缩放尺度，如果动量电荷为非零，我们会发现椭圆远离椭圆形变平的退化基因座。
We analyze the BPS equations in the ``superstratum sector'' of three-dimensional gauged supergravity. We obtain multi-parameter supersymmetric solutions that include elliptical deformations of the supertubes that underlie standard superstrata. We uplift the three-dimensional solutions to obtain the corresponding six-dimensional geometries. This yields new families of elliptically-deformed, ambi-bolar hyper-Kähler geometries in four dimensions with a non-tri-holomorphic $U(1)$ isometry. We also find a new family of scaling superstrata whose S-dual lives entirely within the NS-sector of supergravity, and will thus be more amenable to exact analysis using string probes. In all these new superstrata, including the scaling ones, if the momentum charge is non-zero we find that the ellipse stays away from the degeneration locus in which the ellipse becomes flat.
