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…

Holographic Tests of the Ensemble

Nikolay Bobev, Fridrik Freyr Gautason, Jesse van Muiden

We study in detail a recent proposal stating that M-theory observables arising from the quantisation of M2-branes are naturally computed in a fixed ensemble. In a holographic…

CFTs on Squashed Spheres and the Thermal Effective Action

Klaas Parmentier, Nikolay Bobev

We study three-dimensional CFTs on compact Euclidean manifolds in two complementary limits: small deformations of the round and the small-fiber, large-squashing limit of Seif…

Towards OSV in AdS

Nikolay Bobev, Sunjin Choi, Junho Hong +1

We use supersymmetric localization for 3d SCFTs to establish a relation of the form between the superconformal index and the…

A Holographic Constraint on Scale Separation

Nikolay Bobev, Hynek Paul, Filippo Revello

We propose a new consistency condition for the compatibility of a gravitational effective field theory in AdS with a dual holographic description in terms of a family of large-

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…
