A backreacted bouncing geodesic in 2D
Gauri Batra, Adam Levine, Stephen H. Shenker
In holography, analytically continued finite temperature correlation functions exhibit signatures of the black hole singularity. These take the form of singularities at cert…
Thermodynamic Irreversibility of Training Algorithms
Liu Ziyin, Yuanjie Ren, Adam Levine +1
The training algorithms for AI systems all introduce far-from-equilibrium dynamical processes, and understanding the irreversibility of these algorithms is a fundamental step towar…
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…
Sphere amplitudes and observing the universe's size
Andreas Blommaert, Adam Levine
Sine dilaton gravity is holographically related to DSSYK. We explain how to interpret sine dilaton as 2d quantum cosmology. This paves the way for using two copies of DSSYK as holo…
Wormholes, branes and finite matrices in sine dilaton gravity
Andreas Blommaert, Adam Levine, Thomas G. Mertens +2
We compute the double trumpet in sine dilaton gravity via WdW quantization. The wormhole size is discretized. The wormhole amplitude matches the spectral correlation of a finite-cu…
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…
An entropic puzzle in periodic dilaton gravity and DSSYK
Andreas Blommaert, Adam Levine, Thomas G. Mertens +2
We study 2d dilaton gravity theories with a periodic potential, with special emphasis on sine dilaton gravity, which is holographically dual to double-scaled SYK. The periodicity o…
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-…
Semi-classical dilaton gravity and the very blunt defect expansion
Jorrit Kruthoff, Adam Levine
We explore dilaton gravity with general dilaton potentials in the semi-classical limit viewed both as a gas of blunt defects and also as a semi-classical theory in its own right. W…
