摘要:

我们构造新的超对称解,包括AdS气泡,在N=2截断的五维N=8规范超引力。这种特殊的截断是由N=2规范超重力耦合到两个矢量多重和三个不完整的超多重,最初是在获得规则的AdS气泡几何形状与多个活跃的R-电荷的背景下进行研究。我们专注于相干性的解决方案,对应的对象有两个相等的角动量和三个独立的R-收费。有趣的是,我们发现了一组新的零质量和负质量孤子对AdS_5/Z_k(k \ge 3)的渐近解,它们处处正则,没有封闭的类时曲线.

英文摘要:

We construct new supersymmetric solutions, including AdS bubbles, in an N=2 truncation of five-dimensional N=8 gauged supergravity. This particular truncation is given by N=2 gauged supergravity coupled to two vector multiples and three incomplete hypermultiplets, and was originally investigated in the context of obtaining regular AdS bubble geometries with multiple active R-charges. We focus on cohomogeneity-one solutions corresponding to objects with two equal angular momenta and up to three independent R-charges. Curiously, we find a new set of zero and negative mass solitons asymptotic to AdS_5/Z_k, for k \ge 3, which are everywhere regular without closed timelike curves.
