Thermal superpotential and thermodynamics of neutral hairy black holes in extended SUGRA
Andrès Anabalòn, Dumitru Astefanesei, David Choque +1
We present a family of exact neutral hairy black-hole solutions with spherical horizon topology in extended supergravity with Fayet--Iliopoulos terms. We consider a consistent dila…
Supersymmetric smooth distributions of M2-branes as AdS solitons
A. Anabalón, D. Astefanesei, A. Gallerati +1
We show that the singularities of certain distributions of M2-branes can be removed by adding a Wilson loop around a compact direction along the brane. The holographic coordinate n…

Andrés Anabalón, Mattia Cesàro, Antonio Gallerati +2
The uncharged AdS soliton has been recently shown to be continuously connected to a magnetic, supersymmetric AdS soliton within gauged supergravity. By cons…

Andrés Anabalón, Antonio Gallerati, Simon Ross +1
We consider soliton solutions in AdS with a flat slicing and Wilson loops around one cycle. We study the phase structure and find the ground state and identify supersymmetric…

Introductory Lectures on Extended Supergravities and Gaugings
Antonio Gallerati, Mario Trigiante
In an ungauged supergravity theory, the presence of a \emph{scalar potential} is allowed only for the minimal case. In extended supergravities, a non-trivial scalar potentia…

Andres Anabalon, Dumitru Astefanesei, Antonio Gallerati +1
We consider a , gauged supergravity with an electromagentic Fayet-Iliopoulos term. We restrict to the uncharged, single dilaton consistent truncation and point…
The N>2 supersymmetric AdS vacua in maximal supergravity

We perform a systematic search for anti-de Sitter vacua of maximal supergravity with N>2 residual supersymmetries. We find that maximal supergravity admits two 1-parameter classes…
