Black Holes and Quantumness on Macroscopic Scales
- Physics
- 2013
It has recently been suggested that black holes may be described as condensates of weakly interacting gravitons at a critical point, exhibiting strong quantum effects. In this paper, we study a model…
Black Hole Macro-Quantumness
- Physics
- 2012
It is a common wisdom that properties of macroscopic bodies are well described by (semi)classical physics. As we have suggested this wisdom is not applicable to black holes. Despite being…
Schwarzschild/CFT from soft black hole hair?
- PhysicsJournal of High Energy Physics
- 2019
A bstractRecent studies of asymptotic symmetries suggest, that a Hamiltonian phase space analysis in gravitational theories might be able to account for black hole microstates. In this context we…
Skyrmion Black Hole Hair: Conservation of Baryon Number by Black Holes and Observable Manifestations

Black holes as self-sustained quantum states, and Hawking radiation
- Physics
- 2014
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 from…
Quantum hair and the string–black hole correspondence
- Physics
- 2013
We consider a thought experiment in which an energetic massless string probes a ‘stringhole’ (a heavy string lying on the correspondence curve between strings and black holes) at large enough impact…
Quantum harmonic black holes
- Physics
- 2013
A bstractInspired by the recent conjecture that black holes are condensates of gravitons, we investigate a simple model for the black hole degrees of freedom that is consistent both from the point of…
Black hole quantum mechanics in the presence of species
- Physics
- 2013
Recently within the context of a microscopic quantum theory, the Black Hole's Quantum N‐Portrait, it was shown that continuous global symmetries are compatible with quantum black hole physics. In the…
Regular black holes from semi-classical down to Planckian size
- Physics
- 2017
In this paper, we review various models of curvature singularity free black holes (BHs). In the first part of the review, we describe semi-classical solutions of the Einstein equations which,…

Growing hair on black holes.
- PhysicsPhysical review letters
- 1991
A black hole can carry quantum numbers that are not associated with massless gauge fields, contrary to the spirit of the "no-hair" theorems, but the electric and magnetic cases are closely similar physically.
Black hole's quantum N‐portrait
- Physics
- 2011
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 quantum…

Black holes and large N species solution to the hierarchy problem
- Physics
- 2010
We provide the perturbative and non‐perturbative arguments showing that theories with large number of species of the quantum fields, imply an inevitable hierarchy between the masses of the species…
DYNAMICAL EFFECT OF QUANTUM HAIR
- Physics
- 1991
We show that quantum hair can alter the relation between the temperature and the mass of a black hole. A ZN electric charge on a black hole generates an electric field that is non-perturbative in ħ.…
Nonexistence of baryon number for static black holes
- Physics
- 1972
Wheeler has conjectured that black holes should have no well-defined baryon number, and that as a result the law of conservation of baryons should be transcended in black-hole physics. We show here…
Nonexistence of Baryon Number for Black Holes. II
- Physics
- 1972
In a previous paper we showed that a static (nonrotating) black hole cannot be endowed with exterior scalar-meson or massive vector-meson fields. Here we show that the same is true for massive spin-2…
Classicalization of gravitons and Goldstones
- Physics
- 2011
A bstractWe establish a close parallel between classicalization of gravitons and derivatively-coupled Nambu-Goldstone-type scalars. We show, that black hole formation in high energy scattering…
