First order flows for N=2 extremal black holes and duality invariants
Anna Ceresole, Gianguido Dall'Agata, Sergio Ferrara +1
We derive explicitly the superpotential W for the non-BPS branch of N=2 extremal black holes in terms of duality invariants of special geometry. Although this is done for a one-mod…
Gauged Supergravities from Twisted Doubled Tori and Non-Geometric String Backgrounds
Gianguido Dall'Agata, Nikolaos Prezas, Henning Samtleben +1
We propose a universal geometric formulation of gauged supergravity in terms of a twisted doubled torus. We focus on string theory (M-theory) reductions with generalized Scherk-Sch…
Domain walls, near-BPS bubbles, and probabilities in the landscape
Anna Ceresole, Gianguido Dall'Agata, Alexander Giryavets +2
We develop a theory of static BPS domain walls in stringy landscape and present a large family of BPS walls interpolating between different supersymmetric vacua. Examples include K…
Non-Kaehler attracting manifolds
Gianguido Dall'Agata
We observe that the new attractor mechanism describing IIB flux vacua for Calabi-Yau compactifications has a possible extension to the landscape of non-Kaehler vacua that emerge in…
On the fakeness of fake supergravity
Alessio Celi, Anna Ceresole, Gianguido Dall'Agata +2
We revisit and complete the study of curved BPS-domain walls in matter-coupled 5D, N=2 supergravity and carefully analyse the relation to gravitational theories known as "fake supe…
Gaugino Condensation and Generation of Supersymmetric 3-Form Flux
G. L. Cardoso, G. Curio, G. Dall'Agata +1
We extend the linearised solution of Polchinski and Strassler describing the supergravity dual of the N=1* gauge theory. By analysing the equations of motion of type IIB supergravi…
