Macroscopic origin of the topologically twisted index on

Nikolay Bobev, Vasil Dimitrov, Dario Martelli

We construct a novel family of non-supersymmetric, asymptotically locally AdS solutions of five-dimensional minimal gauged supergravity. In Lorentzian signature the solutions d…

Projecting Gravitational Fluctuations onto Near-Horizon Throats

Alejandro Cabo-Bizet, Vasil Dimitrov, Dario Martelli +1

We show that, for stationary geometries whose linearized fluctuation equations separate into radial and angular Heun equations, a pair of diffeomorphisms projects the full problem…

Patch-wise localization with Chern-Simons forms in five dimensional supergravity

Edoardo Colombo, Vasil Dimitrov, Dario Martelli +1

In this paper, using equivariant localization for foliations, we compute the on-shell action of a general class of supersymmetric solutions of five-dimensional gauged supergravity…

Equivariant localization in supergravity in odd dimensions

Edoardo Colombo, Vasil Dimitrov, Dario Martelli +1

We discuss a localization formula for certain integrals on odd-dimensional manifolds with boundaries, equipped with a Killing vector, and employ this to localize the regularised on…

Branes wrapped on quadrilaterals

Federico Faedo, Alessio Fontanarossa, Dario Martelli

We construct new families of supersymmetric AdS solutions of gauged supergravity and AdS solutions of gauged supergravity, w…

NUTs, Bolts, and Spindles

Matteo Kevin Crisafio, Alessio Fontanarossa, Dario Martelli

We construct new infinite classes of Euclidean supersymmetric solutions of four dimensional minimal gauged supergravity comprising a -invariant asymptotically l…
