Super-Chern-Simons spectra from Exceptional Field Theory

Understand

Exceptional Field Theory has been recently shown to be very powerful to compute Kaluza-Klein spectra.

• Using these techniques, the mass matrix of Kaluza-Klein vector perturbations about a specific class of AdS$_4$ solutions of $D=11$ and massive type IIA supergravity is determined.
• These results are then employed to characterise the complete supersymmetric spectrum about some notable ${\cal N}=2$ and ${\cal N}=3$ AdS$_4$ solutions in this class, which are dual to specific three-dimensional superconformal Chern-Simons field theories.
