AI总结:

本文在$\mathcal{N}=8$规范超引力中,通过构造渐近超代数为容许明确定义渐近Killing旋子的磁性AdS$_4$孤子建立了正能量定理,并解释了不带电AdS$_4$孤子的负能量并不违背该定理。

摘要:

最近研究表明,不带电的AdS$_4$孤子在$\mathcal{N}=8$规范超引力内与磁性的、超对称的AdS$_4$孤子连续相连。通过构造渐近超代数,我们为容许在可缩$S^1$上反周期的、明确定义的渐近Killing旋子的磁性AdS$_4$孤子建立了正能量定理。我们证明,在这些边界条件下,仅存在一个满足该界的离散解,且该界被零能量超对称位形所饱和。尽管不带电的AdS$_4$孤子具有负能量,但它并不违背正能量定理,因为它不容许明确定义的渐近Killing旋子。

英文摘要:

The uncharged AdS$_4$ soliton has been recently shown to be continuously connected to a magnetic, supersymmetric AdS$_4$ soliton within $\mathcal{N}=8$ gauged supergravity. By constructing the asymptotic superalgebra, we establish a positive energy theorem for the magnetic AdS$_4$ solitons admitting well-defined asymptotic Killing spinors, antiperiodic on a contractible $S^1$. We show that there exists only one discrete solution endowed with these boundary conditions satisfying the bound, the latter being saturated by the null energy supersymmetric configuration. Despite having negative energy, the uncharged AdS$_4$ soliton does not contradict the positive energy theorem, as it does not admit well-defined asymptotic Killing spinors.
