Kaluza-Klein spectrometer from exceptional field theory
Speaker:Henning Samtleben
Abstract:I present new tools for the computation of Kaluza-Klein mass spectra associated with compactifications around various background geometries relevant for string theory. This includes geometries with little to no remaining symmetries, hardly accessible to standard methods. The new tools build on exceptional field theory, the duality covariant formulation of supergravity. Among the applications I discuss the tachyonic Kaluza-Klein modes arising at higher levels in the spectrum of the non-supersymmetric SO(3) × SO(3)-invariant AdS4 vacuum of 11-dimensional supergravity.
