Proving the OSV conjecture with the gravitational path integral
Nikolay Bobev, Jan Boruch, Luca V. Iliesiu +1
The OSV conjecture relates the helicity supertrace of black holes in supergravity obtained through a Calabi--Yau compactification of Type IIA string theory to…
When the gravity path integral describes a statistical average
Gabriele Di Ubaldo, Luca V. Iliesiu, Henry W. Lin +1
We find the necessary and sufficient conditions for the gravitational path integral (GPI) to admit an interpretation in terms of (i) an inner product in the Hilbert space of open/c…
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…
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…
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,…
The evaporation of black holes in supergravity
Guanda Lin, Luca V. Iliesiu, Mykhaylo Usatyuk
In supergravity, charged rotating black holes are generically driven towards becoming extremal and supersymmetric through the emission of Hawking radiation. Eventually, as the blac…
The gravitational index of 5d black holes and black strings
Jan Boruch, Roberto Emparan, Luca V. Iliesiu +1
The supersymmetric index of 5d black strings and spinning black holes in M-theory is related to that of 4d black holes in type IIA supergravity when both theories are compactified…
The gravitational path integral from an observer's point of view
Ahmed I. Abdalla, Stefano Antonini, Luca V. Iliesiu +1
One of the fundamental problems in quantum gravity is to describe the experience of a gravitating observer in generic spacetimes. In this paper, we develop a framework for describi…
The evaporation of charged black holes
Adam R. Brown, Luca V. Iliesiu, Geoff Penington +1
Charged particle emission from black holes with sufficiently large charge is exponentially suppressed. As a result, such black holes are driven towards extremality by the emission…
How the Hilbert space of two-sided black holes factorises
Jan Boruch, Luca V. Iliesiu, Guanda Lin +1
In AdS/CFT, two-sided black holes are described by states in the tensor product of two Hilbert spaces associated with the two asymptotic boundaries of the spacetime. Understanding…
On the non-perturbative bulk Hilbert space of JT gravity
Luca V. Iliesiu, Adam Levine, Henry W. Lin +2
What is the bulk Hilbert space of quantum gravity? In this paper, we resolve this problem in 2d JT gravity, both with and without matter, providing an explicit definition of a non-…
New forms of attraction: Attractor saddles for the black hole index
Jan Boruch, Luca V. Iliesiu, Sameer Murthy +1
The count of microstates for supersymmetric black holes is typically obtained from a supersymmetric index in weakly-coupled string theory. We find the saddles in the gravitational…
Constructing all BPS black hole microstates from the gravitational path integral
Jan Boruch, Luca V. Iliesiu, Cynthia Yan
Understanding how to prepare and count black hole micro-states by using the gravitational path integral is one of the most important problems in quantum gravity. Nevertheless, a st…
The Gross-Neveu-Yukawa Archipelago
Rajeev S. Erramilli, Luca V. Iliesiu, Petr Kravchuk +3
We perform a bootstrap analysis of a mixed system of four-point functions of bosonic and fermionic operators in parity-preserving 3d CFTs with O(N) global symmetry. Our results pro…
Revisiting the Logarithmic Corrections to the Black Hole Entropy
Luca V. Iliesiu, Sameer Murthy, Gustavo J. Turiaci
Logarithmic corrections to the entropy of extremal black holes have been successfully used to accurately match degeneracies from microscopic constructions to calculations of the gr…
Black hole microstate counting from the gravitational path integral
Luca V. Iliesiu, Sameer Murthy, Gustavo J. Turiaci
Reproducing the integer count of black hole micro-states from the gravitational path integral is an important problem in quantum gravity. In this paper, we show that, by using supe…
Alpha states demystified: Towards microscopic models of AdS holography
Andreas Blommaert, Luca V. Iliesiu, Jorrit Kruthoff
We continue our study of factorizing theories of dilaton gravity, characterized by a universal bilocal interaction. All such factorizing theories can be shown to have discrete spec…
BPS and near-BPS black holes in and their spectrum in SYM
Jan Boruch, Matthew T. Heydeman, Luca V. Iliesiu +1
We study quantum corrections in the gravitational path integral around nearly -BPS black holes in asymptotically space, dual to heavy states in 4D $\mathca…
Gravity factorized
Andreas Blommaert, Luca V. Iliesiu, Jorrit Kruthoff
We find models of two-dimensional gravity that resolve the factorization puzzle and have a discrete spectrum, whilst retaining a semiclassical description. A novelty of these model…
The volume of the black hole interior at late times
Luca V. Iliesiu, Márk Mezei, Gábor Sárosi
Understanding the fate of semi-classical black hole solutions at very late times is one of the most important open questions in quantum gravity. In this paper, we provide a path in…
