Kaluza-Klein Spectrometry for String Theory Compactifications.
I will present a powerful new method that for the first time allows us to compute the Kaluza-Klein spectrum of a large class of string theory compactifications. This includes geometries with little to no remaining (super-)symmetries, completely inaccessible by previous methods. I will show how these insights can be used to compute the anomalous dimensions of protected and unprotected operators in strongly-coupled CFTs, as well as to study global properties of their conformal manifolds. I will also show how the method can be used to determine the perturbative stability of non-supersymmetric AdS vacua. This reveals that tachyons can arise from higher Kaluza-Klein modes that are not visible in lower dimensions. Intriguingly, there are also classes of fully perturbatively stable non-supersymmetric AdS vacua in 10-d supergravity.
