Description

Exceptional Field Theory provides a natural framework to study compactification of 10/11D maximal supergravities. This tool allowed us to build new AdS${}_4$ solutions by providing consistent truncations of Type IIB supergravity to $\mathcal{N}=8$ $D=4$ gauged supergravities. In this talk, we will review some AdS${}_4\times S^1\times S^5$ solutions of Type IIB supergravity called “S-folds” as well as new $\mathcal{N}$=2 black-hole solutions with such asymptotic geometry. We will show how we can deform these solutions to obtain exactly marginal, stable, non-supersymmetric deformations, in tension with the non-susy AdS conjecture. Finally, we will present a new consistent truncation of Type IIB supergravity to pure $D=4$ $\mathcal{N}=4$ supergravity. This could be used to uplift several families of $D=4$ solutions in the existing literature, so far thought to originate only from a truncation of M-theory on $S^7$.
