研究了 Calabi-Yau 黑洞中 N 探针 D0 膜的构型。发现了近视界束缚态的大简并性，可以将其描述为平铺黑洞视界的最低朗道能级。这些状态保留了近地平线 AdS2 × S2 × CY3 吸引子几何结构的一些增强的超对称性，但不保留完全渐近平坦解的超对称性。构建超对称非阿贝尔构型，通过迈尔斯效应，产生与包裹 CY3 周期的高维膜相关的电荷。明确构建了描述吸引子几何中的 D0 膜的 SU(1,1|2) 超共形量子力学。
Configurations of N probe D0-branes in a Calabi-Yau black hole are studied. A large degeneracy of near-horizon bound states are found which can be described as lowest Landau levels tiling the horizon of the black hole. These states preserve some of the enhanced supersymmetry of the near-horizon AdS2 × S2 × CY3 attractor geometry, but not of the full asymptotically flat solution. Supersymmetric non-abelian configurations are constructed which, via the Myers effect, develop charges associated with higher-dimensional branes wrapping CY3 cycles. An SU(1,1|2) superconformal quantum mechanics describing D0-branes in the attractor geometry is explicitly constructed.
