A note on the quantization of angular momentum for black holes
Jon Goker, Luca V. Iliesiu, Elisa Tabor
We argue that the gravitational path integral for rotating black holes is periodic in the angular velocity, implying the quantization of angular momentum in arbitrary dimensions fo…
Positivity of the gravitational path integral implies the axionic weak gravity conjecture
Gabriele Di Ubaldo, Luca V. Iliesiu, Henry W. Lin +1
The gravitational path integral can compute inner products between different states of open and closed universes. To have a well-defined Hilbert space, these inner products should…
Consistent Evaluation of the No-Boundary Proposal
Ahmed I. Abdalla, Stefano Antonini, Raphael Bousso +3
We revisit the Hartle-Hawking no-boundary proposal. To extract probabilities, one must use the gravitational path integral (GPI) to compute not only the no-boundary amplitude, but…
Novel black saddles for 5d gravitational indices and the index enigma
Jan Boruch, Roberto Emparan, Luca V. Iliesiu +1
We construct a series of novel Euclidean multi-black-hole, black ring, black Saturn, and black lens solutions to supergravity that contribute as saddle-points to the grav…
A Black Hole Airy Tail
Stefano Antonini, Luca V. Iliesiu, Pratik Rath +1
In Jackiw-Teitelboim (JT) gravity, which is dual to a random matrix ensemble, the annealed entropy differs from the quenched entropy at low temperatures and goes negative. However,…
Multicentered black hole saddles for supersymmetric indices
Jan Boruch, Luca V. Iliesiu, Sameer Murthy +1
The supersymmetric index in string theory can sometimes have a discontinuous integer-valued jump at co-dimension one surfaces in moduli space called walls of marginal stability. Wh…
