Mattia Cesàro, Gabriel Larios, Oscar Varela

摘要:

本文分析了最近发现的IIB型超引力的典型非几何S-折叠型${\cal N}=1$ AdS $_4$解的三个不同族上的Kaluza-Klein激发谱,给出了它们谱的完整代数结构,包括在所有Kaluza-Klein能级上的OSp $(4|1)$多重态的含量以及它们在剩余对称群下的电荷.我们还提供了广泛的结果,多重维度使用新的方法来自例外场论,包括完整的,分析结果的家庭之一。所有这三个频谱显示周期性的模量,标签相应的家庭的解决方案。最后,在某些情况下,在完全成熟的IIB型提升的解决方案的水平,这些模量的紧凑性进行了验证。

英文摘要:

We analyse the spectrum of Kaluza-Klein excitations above three distinct families of ${\cal N}=1$ AdS$_4$ solutions of type IIB supergravity of typically non-geometric, S-fold type that have been recently found. For all three families, we provide the complete algebraic structure of their spectra, including the content of OSp$(4|1)$ multiplets at all Kaluza-Klein levels and their charges under the residual symmetry groups. We also provide extensive results for the multiplet dimensions using new methods derived from exceptional field theory, including complete, analytic results for one of the families. All three spectra show periodicity in the moduli that label the corresponding family of solutions. Finally, the compactness of these moduli is verified in some cases at the level of the fully-fledged type IIB uplifted solutions.
