Abstract:

The spectrum of single-trace operators of holographic CFTs at strong coupling and large N can be mapped to the spectrum of Kaluza-Klein (KK) excitations over the dual AdS supergravity solutions. Unfortunately, computing these KK spectra is usually a prohibitively difficult task even for the simplest AdS solutions. In this talk, I will introduce new spectral methods based on Exceptional Field Theory that, for certain AdS/CFT dual pairs, bypass all difficulties and reduce the KK spectral problem to a simple diagonalisation of suitable mass matrices. I will illustrate these methods for a class of super-Chern-Simons CFT3s with AdS4 duals in M-theory and type IIA string theory.
