Kaluza-Klein spectrometry for \({\rm AdS_{3}}\) vacua

We use exceptional field theory to compute Kaluza-Klein mass spectra around \({\rm AdS_{3}}\) vacua that sit in half-maximal gauged supergravity in three dimensions. The formalism applies to any vacuum that arises from a consistent truncation of higher-dimensional supergravity, no matter what symmet...

Description
Summary:We use exceptional field theory to compute Kaluza-Klein mass spectra around \({\rm AdS_{3}}\) vacua that sit in half-maximal gauged supergravity in three dimensions. The formalism applies to any vacuum that arises from a consistent truncation of higher-dimensional supergravity, no matter what symmetries are preserved. We illustrate its efficiency by computing the spectra of \({\cal N}=(2,0)\) and \({\cal N}=(1,1)\) six-dimensional supergravities on \({\rm AdS_{3}}\times S^{3}\) and of type II supergravity on \({\rm AdS_{3}}\times S^{3}\times S^{3}\times S^{1}\).
