具有增强超对称性的IIB型薛定谔不变解

Schrodinger invariant solutions of type IIB with enhanced supersymmetry

Aristomenis Donos, Jerome P. Gauntlett

摘要:

我们构造了一类在非相对论薛定谔代数下不变的IIB型超引力超对称解的Killing旋量。这些解依赖于一个五维的Sasaki-Einstein空间,并且已经证明它们允许两个Killing旋量。在这里,我们将表明,对于一般的Sasaki-Einstein空间,有特殊的子类的解决方案,承认六个Killing旋量,我们确定相应的超等距代数。我们还证明了Sasaki-Einstein空间是圆五球的特殊情况下,Killing旋量的数目可以增加到12。

英文摘要:

We construct the Killing spinors for a class of supersymmetric solutions of type IIB supergravity that are invariant under the non-relativistic Schrodinger algebra. The solutions depend on a five-dimensional Sasaki-Einstein space and it has been shown that they admit two Killing spinors. Here we will show that, for generic Sasaki-Einstein space, there are special subclasses of solutions which admit six Killing spinors and we determine the corresponding superisometry algebra. We also show that for the special case that the Sasaki-Einstein space is the round five-sphere, the number of Killing spinors can be increased to twelve.
