Gravitational backgrounds, such as black holes, AdS, de Sitter and inflationary universes, should be viewed as composite of N soft constituent gravitons. It then follows that such systems are close to quantum criticality of graviton Bose-gas to Bose-liquid transition. Generic properties of the ordinary metric description, including geodesic motion or particle-creation in the background metric, emerge as the large-N limit of quantum scattering of constituent longitudinal gravitons. We show that… Expand

Black holes as self-sustained quantum states, and Hawking radiation
We employ the recently proposed formalism of the “horizon wave-function” to investigate the emergence of a horizon in models of black holes as Bose-Einstein condensates of gravitons. We start fromExpand
De Sitter space as BRST invariant coherent state of gravitons
The S-matrix formulation indicates that a consistent embedding of de Sitter state in quantum gravity is possible exclusively as an excited quantum state constructed on top of a valid S-matrix vacuumExpand
On corpuscular theory of inflation
In order to go beyond the mean-field approximation, commonly used in the inflationary computations, an identification of the quantum constituents of the inflationary background is made. InExpand
Emergence of a dark force in corpuscular gravity
We investigate the emergent laws of gravity when dark energy and the de Sitter space-time are modeled as a critical Bose-Einstein condensate of a large number of soft gravitons NG. We argue that thisExpand
Black Hole Formation and Classicalization in Ultra-Planckian 2 ! N Scattering
We establish a connection between the ultra-Planckian scattering amplitudes in field and string theory and unitarization by black hole formation in these scattering processes. Using as a guideline anExpand
Thermal BEC Black Holes
TLDR
Corrections to the Klein–Gordon equation for a toy graviton field coupled to a static matter current in a spherically-symmetric setup suggest that for black holes in this quantum state, the evaporation properly stops for a vanishing mass. Expand

TLDR
An S-matrix formulation of Einstein gravity, such as string theory, nullifies an outstanding cosmological puzzle and discusses possible observational signatures which are especially interesting in theories with a large number of particle species. Expand
On the substructure of the cosmological constant
We summarize the findings of our paper $\tt \small arXiv:1701.08776$ $\tt \small[hep-th]$. We start by defining the quantum break-time. Once one understands a classical solution as expectation valueExpand
Horizon Quantum Mechanics: a hitchhiker's guide to quantum black holes
It is congruous with the quantum nature of the world to view the space-time geometry as an emergent structure that shows classical features only at some observational level. One can thus conceive theExpand
Effective fluid description of the dark universe
Abstract We propose an effective anisotropic fluid description for a generic infrared-modified theory of gravity. In our framework, the additional component of the acceleration, commonly attributedExpand

We establish a quantum measure of classicality in the form of the occupation number, $N$, of gravitons in a gravitational field. This allows us to view classical background geometries as quantumExpand
