通量紧化的近地平线几何

Near-Horizon geometry from flux compactification

Oscar Loaiza-Brito, Liliana Vazquez-Mercado

摘要:

我们研究了任意通量配置必须满足的条件,以便从包含NS-NS通量的IIB型超重力通量紧化中构造$AdS_2\times S^2$型4D时空。我们提出了一个解决方案,包括在3-形式NS-NS和RR通量的存在下的紧化。内部流形是SU(3)结构的六维流形,具有零曲率和挠率。通过在四维低能理论中保持两个超对称性,我们找到了一种在非Calabi-Yau流形中通过紧化得到$AdS_2\times S^2$几何作为近视界解的方法.

英文摘要:

We study the conditions an arbitrary flux configuration must fulfill in order to construct a 4d space-time of the type $AdS_2\times S^2$ from a type IIB supergravity flux compactification in which NS-NS fluxes are included. We present a solution consisting on a compactification in the presence of 3-form NS-NS and RR fluxes. The internal manifold is a SU(3) structure six-dimensional manifold, with null curvature and with torsion. By preserving two supersymmetries in the four-dimensional low energy theory, we find a way to obtain the $AdS_2\times S^2$ geometry as a near-horizon solution by compactification in non-Calabi-Yau manifolds.
