Description

I will show, using triality, that there are three different consistent ${\rm AdS}_3\times S^3$ truncations of half-maximal six-dimensional supergravity, one for ${\cal N}=(2,0)$ and two for ${\cal N}=(1,1)$. One of latter has never been studied, and I will demonstrate that it results in a three-dimensional half-maximal theory with a number of interesting features, revealed by recent spectroscopy techniques based on Exceptional Field Theory. Among them, I will present a non-supersymmetric two-parameter family of ${\rm AdS}_{3}$ vacua that enjoys pertubative stability of the full Kaluza-Klein tower. From the two ${\cal N}=(1,1)$ truncations, I will finally illustrate that there is no absolute notion of Kaluza-Klein level.
