SolutionsX: supergravity theories/solutions as code, with an agentic workflow for machine-verifiable physics
Vasil Dimitrov
A supergravity solution in the literature is an artifact that cannot be verified without re-deriving it: conventions might not be clearly stated, papers have typos, algebra is tedi…
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…
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…
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…
