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…

AdS Black Holes and Holography

Nikolay Bobev, Marina David, Vasil Dimitrov +1

We present a detailed study of the regularized on-shell action of the recently found asymptotically AdS black hole supergravity solution with three angular momenta and two elec…
