    On the correspondence between black holes, domain walls and fluxes

    We revisit and extend the correspondence between black holes, domain walls and fluxes in type IIA compactifications. We argue that these three systems can be described by the same supergravity effective action...

    Islands and light gravitons in type IIB string theory

    We consider the setup of a black hole in AdS4 coupled to an external bath, embedded in type IIB string theory. We study quantum extremal islands in these backgrounds, in relation to the existence of a massive gra...

    τRR minimization in presence of hypermultiplets

    We compute τRR minimization in gauged supergravity for M-theory and String Theory truncations with both massless and massive vector multiplets. We explicitly compute, as anticipated in [1], that massive vector fi...

    On AdS7 stability

    AdS7 supersymmetric solutions in type IIA have been classified, and they are infinitely many. Moreover, every such solution has a non-supersymmetric sister. In this pa- per, we study the perturbative and non-p...

    Holographic duals of 6d RG flows

    A notable class of superconformal theories (SCFTs) in six dimensions is parameterized by an integer N , an ADE group G, and two nilpotent elements μL,R in G. Nilpotent elements have a natural partial ordering, wh...

    Interactions resolve state-dependence in a toy-model of AdS black holes

    We show that the holographic description of a class of AdS black holes with scalar hair involves dual field theories with a double well effective potential. Black hole microstates have significant support arou...

    Rholography, black holes and Scherk-Schwarz

    Supersymmetric black holes in AdS4 from very special geometry

    Supersymmetric black holes in AdS spacetime are inherently interesting for the AdS/CFT correspondence. Within a four dimensional gauged supergravity theory coupled to vector multiplets, the only analytic solut...

    Rotating black holes in 4d gauged supergravity
