G. Papadopoulos, J. Phillips

AI总结:

该研究提出IIA型AdS背景的扭协变形式层级(TCFHs),证明Killing旋量形式双线性量满足相关推广方程,探究其性质并揭示其与自旋粒子探针隐藏对称性的关联。

摘要:

我们提出了经过翘曲的(有质量的)IIA型AdS背景的扭协变形式层级(twisted covariant form hierarchies,TCFHs)。由此我们证明,所有Killing旋量形式双线性量都满足关于TCFH联络的共形Killing-Yano方程的推广形式。我们还探究了TCFH的若干性质,包括通用背景下最小TCFH联络的约化和乐群。此外,我们研究了TCFH与在IIA型AdS背景上传播的探针的隐藏对称性之间的相互作用。我们发现,一类IIA相交膜构型的视界附近几何的部分Killing旋量形式双线性量是Killing-Yano形式,因此能为自旋粒子探针生成隐藏对称性。

英文摘要:

We present the twisted covariant form hierarchies (TCFHs) of warped (massive) IIA AdS backgrounds. As a consequence we demonstrate that all Killing spinor form bilinears satisfy a generalisation of the conformal Killing-Yano equation with respect to the TCFH connections. We also explore some of the properties of TCFHs which include the reduced holonomy of the minimal TCFH connections for generic backgrounds. Furthermore, we investigate the interplay between TCFHs and hidden symmetries of probes propagating on IIA AdS backgrounds. We find that some of the Killing spinor form bilinears of near horizon geometries of a class of IIA intersecting brane configurations are Killing-Yano forms and so generate hidden symmetries for spinning particle probes.
