标题： D-brane Construction of the 5D NHEK Dual

摘要： 考虑在IIb型弦理论中将K\(^3\)×S\(^1\)紧化到五维的具有SU(2)\(_L\)自旋的极端但非超对称带电黑洞。这些黑洞具有一个近似视界或NHEK区域，该区域内增强了SL(2,R)\(_L\)共形对称性。结果显示，NHEK几何结构存在第二种不等价的渐近平坦延拓，在这种延拓中S\(^1\)的半径变为无穷大，而SU(2)\(_L\)轨道角圆的半径趋于常数。与第二种解相关的渐近荷将其识别为一种带有特定非零世界体积荷密度、温度和化学势的5D D1-D5-Taub-NUT黑洞弦。然后确定NHEK几何结构的对偶是此缠绕膜构型的红外极限。 显示英文摘要

摘要： Extremal but non-supersymmetric charged black holes with SU(2)_L spin in IIB string theory compactified to five dimensions on K^3 x S^1 are considered. These have a near-horizon or NHEK region with an enhanced SL(2,R)_L conformal symmetry. It is shown that the NHEK geometry has a second, inequivalent, asymptotically flat extension in which the radius of the S^1 becomes infinite but the radius of the angular circles of SU(2)_L orbits approach a constant. The asymptotic charges associated to the second solution identify it as a 5D D1-D5-Taub-NUT black string with certain nonzero worldvolume charge densities, temperatures and chemical potentials. The dual of the NHEK geometry is then identified as an IR limit of this wrapped brane configuration.
